FAQ


In the FAQ section of our PDF to Word Converter PDF program you will find a question and answer catalog that we will constantly expand with the time and if necessary to new topics.

To unfold, please click on the following panels:

Invalid floating-point operation

This error occurs very rarely, but, in this case, please alter the conversion mode of the PDF to Word converter from the standard setting ‘automatic conversion mode (default)’ to a user-defined mode!

It would be best to use the user-defined conversion with tabs here. After altering the conversion mode, please try to convert the PDF to Word again.

If necessary, you should alter further settings options on the ‘advanced settings’ tab if the problem occurs again. You can try to further specify the extraction options to exclude the incompatible content of the PDF document from the conversion during the PDF to Word transfer.

This error occurs when PDF2Word Converter automatically tries to open Word, OpenOffice or LibreOffice following successful conversion, despite the respective program already being open.

The opened text processing software may even block the creation of the converted Word file. If this error occurs, you should ensure that Word etc. has not been launched. Then try again. This should rectify the problem.

In this case, switch the conversion mode to “Reformat document (reflow)” and try again.

When the layout has not been transferred cleanly to Word, the error is generally not due to 7-PDF2Word. The problem usually lies with the PDF file itself, i.e. it contains errors, is defective etc.

To solve this problem, we have added an automatic repair and optimisation routine to our PDF printer software, 7-PDF Printer, which automatically repairs PDF documents when printing again to PDF (via Acrobat Reader or other PDF viewers).

The newly created file can then usually be converted with 7-PDF2Word without losing the layout.

Presumably, her original PDF file contained only image information. So pictures that were saved in a PDF. A good example of this would be a PDF generated by a fax machine or scanner. These devices only "capture" the contents of a printed paper and save it as a PDF file, but without actually saving the content in platform-independent, vectorized digital information in the form of a "real" PDF file. And exactly this content you get in Word. So an image that was in the PDF document. Since Word is not a graphics application, you can not edit this image data.

You may NOT be able to produce editable Word documents if one of the following conditions applies:

  • The PDF was created by a scanner
  • The PDF is a form

* A scan to PDF simply embedds an image into the PDF. We would say, it's a PDF bluff package - however, you do not what the content from the PDF, rather from the image! So the method is not PDF2Word, rather OCR2Word.


If you have further questions about the program, please contact our free eMail support. Otherwise, we wish you much pleasure with our PDF to Word Converter!


In the FAQ section of our PDF printer you will find a list of questions and answers that we will be expanding over time and to include new topics as needed.

Yes, if the printer is installed normally by an administrator then all users can use the printer.

If you define links in your document inside a program such as Microsoft Word then only the text is printed to the PDF file. The Adobe PDF Reader will recognize a text that shows a valid hyperlink and underline that text. This means that you have to type the entire web address or email address for the text to be recognized as a link in the resulting document.

All editions of Microsoft Windows 7, 8, 8.x, 10, 11 as well as Microsoft Windows Server 2012 to 2022.

Yes. It works on both 32 and 64 bit operating systems. The setup program looks at your system and decides to install either the 64 or 32 bit driver.

There is an MSI file available at the download page.

This error can occur under Windows Vista if you have a corrupt driver cache file. Try deleting C:\Windows\inf\INFCACHE.1 and run the setup program again.

Just run the installation program and install the new one on top of the old one.

The license is a license.xml file that you simply copy to the program folder. This is the folder where gui.exe is located. Detailed installation instructions can be found in the documentation for the PDF printer.

This is "by design" from Microsoft and started with Windows 7. There is a workaround for this design from Microsoft: http://support.microsoft.com/kb/2015694

Yes. There are a lot of different parameters supported by the setup program that will control an unattended installation.

There is no need for a trial license. The version you can download has all the functionality already. Nothing is blocked because you don't have a license. You can just download the product and test everything before you decide to buy.

We have an Excel sheet with all the texts in the program. You can request this file and help us translate the program into your language.

You will find support for PDF 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, and 1.7.

The printer supports the following formats: Letter, Ledger, Legal, A3, A4, A5, 11x17, Note, A2, A6, LetterSmall, A0, A1, A4Small, A7, A8, A9, A10, ISO B0, ISO B1, ISO B2, ISO B3, ISO B4, ISO B5, ISO B6, JIS B0, JIS B1, JIS B2, JIS B3, JIS B4, JIS B5, JIS , 6, C0, C1, C2, C3, C4, C5, C6, ARCHE, ARCHD, ARCHC, ARCHB, ARCHA, ARCHE1, ARCHE1 Half, FLSA, FLSE, HalfLetter, PA4.

You can define your own paper size if none of the listed formats fits your need.

Yes. You can set the file name in the options dialog. The options dialog is located in the start menu of your computer.

Open the options dialog from the start menu and change the File Name option to something like <personal> \ <smarttitle> .pdf. Das <personal> macro refers to the My Documents folder. You may want to remove the check mark in the Remember last folder option.

The fast answer is no. The problem is that all the PDF writer sees is a print job generated by the printing application. A print job does not contain any information that will link it to the original document.

Watermarks are placed under the print that you make. Some programs such as Internet Explorer prints a white background instead of leaving the background transparent. The white background blocks the view of the watermark. Other programs such as Microsoft Word leave the background transparent and you can see the watermark.

The PDF printer offers the extracttext setting for this, which extracts the print data and then makes it readable via the VBScript event handler and macro programming. If you don't have programming skills, you can also use our standard solution, the 7-PDF Mailer PlugIn. This PlugIn enhances the functionality of the PDF printer by enabling comprehensive control codes processing and automatic detection.

In this FAQ section for 7-PDF Attach Extract and Remove, you'll find answers to common questions about usage, integration, and licensing – especially in connection with the integrated 7-PDF Invoice Extractor. We continuously expand this section as needed.

Click on a question below to expand the answer:

This tool lets you attach, extract, and remove embedded files from PDF documents. It's ideal for handling PDF/A-3 e-invoices compliant with the ZUGFeRD standard. It can be used via the graphical interface (GUI) or through the command line (CLI).

Yes, starting from version 2.0! The tab "PDF Invoice to PDF ZUGFeRD" allows you to automatically analyze a standard PDF invoice using our 7-PDF Invoice Extractor. The AI identifies all relevant data and generates an XML file (factur-x.xml) according to EN 16931, which is then embedded into the PDF. Even scanned PDF invoices are read and supported by OCR recognition!

Only if your PDF invoice is not yet in PDF/A-3 format. In that case, you’ll need our 7-PDF Printer Professional to prepare it properly. This is often required in ERP print jobs or when generating PDFs from Word/Excel that include letterhead or embedded graphics.

After creating a PDF/A-3 invoice using 7-PDF Printer, 7-PDF Attach Extract and Remove is triggered automatically. There, the Invoice Extractor generates the ZUGFeRD XML file and embeds it into the PDF. This integration works through a print workflow and a simple command-line call with parameters.

See the step-by-step integration guide

The program runs on Windows 7 SP1 or later (32/64-bit) and is compatible with Windows 10, 11, and all major Windows Server versions. It works out of the box and requires no additional PDF software.

To use 7-PDF Attach Extract and Remove, a valid single or volume license is required (Named-User model). The integrated 7-PDF Invoice Extractor is included – along with 25 free conversions.

For higher volumes or long-term use, we recommend a monthly API subscription with token, which can be cancelled at any time.

If you plan to generate ZUGFeRD invoices via print workflow, you’ll also need a 7-PDF Printer Professional license. For structural validation, we recommend the 7-PDF E-Invoice Validator.

Yes. To ensure compatibility with recipient systems (e.g. government portals or accounting software), the embedded XML file must be named factur-x.xml. The tool handles this automatically for you.

Use our 7-PDF E-Invoice Validator to verify structure, syntax, and compliance with EN 16931.

Yes! You can use the command-line mode (-mode "console") with parameters such as -usage "attach" or "generate" to integrate it into PowerShell, batch scripts, or scheduled tasks.

In such cases, the Invoice Extractor may not generate XML, or only a partial one. Make sure your invoice includes key fields like recipient, IBAN, VAT ID, invoice date, and totals. These cases are logged internally.

Open the PDF in a viewer (e.g. Adobe Reader) and check the document properties. Under “Standards”, it should mention “PDF/A-3b”. Alternatively, you can use the 7-PDF E-Invoice Validator to confirm.

Yes. Use the CLI or a PowerShell/batch script to process complete folders automatically – ideal for incoming invoices from ERP, email, or scanner sources.

The API token you used is either expired (e.g. by canceling the subscription) or invalid. Please check your subscription or log in at https://generator.7-pdf.de/login to review your token and quota.

Yes. All data is transmitted exclusively via secure HTTPS (SSL/TLS) to our servers located in Germany. No unencrypted communication is used at any point.

Our AI-powered analysis platform was developed entirely in-house and runs on our own server infrastructure located in Germany.

Your PDF invoices and all associated content are immediately deleted after successful processing. No storage, logging, or transfer of data takes place.

7-PDF is a sole proprietorship based in Germany and operated under personal liability. We are not an anonymous GmbH or Ltd. As developer and operator, we personally stand behind quality, security, and data protection.

In the FAQ for the 7-PDF E-Invoice Validator, we answer frequently asked questions regarding functionality, usage, licensing, and technical integration. This page is continuously updated as needed.

Click a question to view the answer:

The validator checks whether the embedded XML in a PDF invoice meets the formal requirements of the DIN EN 16931 standard. It supports formats such as ZUGFeRD and XRechnung. The validator generates a detailed audit report and a human-readable visual view of the e-invoice. This allows e-invoices to be checked for structural and content integrity.

The validator only supports formats and versions that are currently accepted for tax-compliant electronic invoicing. Outdated standards are intentionally not supported.

  • XRechnung 3.0.2 (UBL/CII)supported
  • Factur-X 1.0.07 Extended (2.3.1)supported
  • Peppol BIS 3.0.18supported
  • ZUGFeRD 2.1.x / 2.2.xstill valid
  • XRechnung 2.0 / 2.1deprecated
  • Other experimental formatsnot permitted

If you upload a non-supported format, the report may include a message like "no valid validation scenario available". Please ensure your invoices use current and approved formats.

“Passed” means the embedded XML fully met the validation requirements. “Failed” indicates structural issues such as missing mandatory fields or invalid elements. The validation report provides detailed error descriptions.

Yes. Using the command line (-mode "console"), you can validate entire folders automatically. Integration into existing scripts or workflows is also supported.

Yes. The validator displays whether the uploaded file conforms to the PDF/A-3 standard – a requirement for compliant ZUGFeRD and XRechnung invoices.

No, no permanent storage takes place. The 7-PDF E-Invoice Validator is a server-based service that runs for technical reasons (Java/XRechnung components) on our own infrastructure located in Germany.

Your PDF is transmitted via encrypted HTTPS (SSL/TLS). The validation takes place exclusively on our servers, and the file is automatically and permanently deleted after processing.

The service is operated with personal liability by a German sole proprietorship. View imprint.

Read the validation report carefully. It provides specific details about invalid or missing XML elements. Check mandatory fields, currency codes, and the XML structure.

Yes. The validator supports command-line use (CLI) and can be easily integrated into scripts, batch processing, or ERP automation.

You need a valid single or volume license (Named User model). The license is perpetual. For batch processing, we recommend volume or enterprise licenses.

Below are some general FAQs about the ordering, handling and cross-product use of our products.

All our PDF programs have been developed for Windows 11, 10, 8.1, 8, 7, Vista, XP and for Windows Server 2022, 2019, 2016, 2012, 2008, 2003.

Definitely not! All our paid programs are not subject to subscription compulsion. With us you receive only Lifetime licenses. Our low-priced license fees will only be charged once for all our paid programs! This sets us apart from many other PDF providers.

Yes, all our programs run directly in the functionalities of the freeware variants, which usually contains all the functions you want to test. All programs can therefore be extensively tested before upgrading to a PRO variant. You basically never buy the cat in a poke.

Yes, but only for our commercial PDF programs. For our PDF Printer 7-PDF Printer this option is optional for customers, for example from the company licensing. For group licenses of our other commercial PDF products, we optionally offer maintenance contracts upon customer request. All other users can contact our non-binding english-speaking support in case of problems, this is generally available free of charge.

No, all our programs are provided purely electronically. We do not ship software boxes and paper manuals. Alone for cost reasons. We prefer to pass these savings on to them - through cheap and fair license prices.

Companies, authorities and associations can order directly from us. We offer all other licensees an online license purchase through our distributor share-it Digital Rivers. The payment method available is PayPal as well as credit card and bank transfer. The accounting is done after the purchase here by shareIt and not by us.

No. All our programs are installed locally on your system and do not require internet connection. Not even for the licensing process and certainly not for the daily work with their files! What is stored on your systems stays on your systems.

You can always download our programs in their latest version from our website. The installed programs can then be automatically converted to the licensed full or pro version by entering a license key. However, you will receive this via e-mail after purchase, and thus electronically, an exact guide. A new installation is no longer necessary. Your invoice will also be sent to you by e-mail as PDF.
