Which Windows version do I need to run PDF Annotator?

With its focus on annotation, PDF Annotator cannot cover every aspect of PDF.

Some limitations are:

• Adobe® DRM protected documents cannot be opened. However, this does not refer to documents that just require a user or owner password.
• Documents protected by digital signatures cannot be opened. Digital Signatures are not supported.
• Under some conditions, AES-128 encrypted documents cannot be opened.
• Windows on ARM: The Print to PDF Annotator feature is not available on devices running on ARM processors.

Please also consult our Bulletins et avertissements de sécurité.

Unfortunately not. PDF Annotator requires Microsoft Windows.

We have currently no plans for supporting additional operating systems.

Windows on ARM is supported with restrictions.

If your device runs on Windows 11/10 in S Mode, you will need to switch out of S mode in Windows 11/10.

Windows in S Mode cannot run fully featured desktop applications like PDF Annotator.

You will need to switch to Windows 11/10 Home or Windows 11/10 Pro in order to run PDF Annotator.

Switching off S mode is usually free and only takes a couple of minutes.

Please follow Microsoft's instructions for Switching out of S mode in Windows.

There is no SDK or embeddable component available or planned at this time. What you can do, and we have many integrators going that way, is to run PDF Annotator from within your application on the command line.

Depending on your requirements, there are a couple of undocumented features to customize and restrict the UI, and you can wait for the process, or set a copy hook on the file you opened, to get notified once it is written. Also, we offer customization, depending on what exactly you would need. Please contact us for details if this would be an option for you.

Just download and install the previous PDF Annotator version from our download archive and unlock it using your existing PDF Annotator license key.

I have lost my license key, what can I do?

After an upgrade, we will copy all your settings from the existing installation, including your custom tools and stamps in the toolbox.

If you customized the menus and toolbars in the old version, these changes will not be copied on major version upgrades. The new version will include new menu items and toolbar buttons, so a reset of the menu and toolbar system is required. This only applies to major upgrades (like from version 8 to Version 9), and only affects menus and toolbars (not your tools and stamps in the toolbox).

As a system administrator you need to deploy PDF Annotator under a multi-user license on a large number of devices.

Please refer to our Silent Install Guide.

We support and provide bug fixes and security updates for the current major version (currently: PDF Annotator 9), and the previous major version (currently: PDF Annotator 8).

We offer a 30-day trial version on our Download Page.

The 30-day trial is fully functional with one limitation: Documents saved with the trial version contain a trial notice on the top of each page.

The trial notice can be removed by re-opening and re-saving the documents with a licensed version of PDF Annotator.

If you wish to try PDF Annotator without this limitation, please consider buying a license, and taking advantage of our 60-day Money-Back Guarantee.

If you get asked for a username and a password (or email address and password) when trying to install PDF Annotator, this question comes from your operating system (Windows), not from PDF Annotator.

To install PDF Annotator, you need to have Administrator rights on your computer.

If you do not have Administrator rights, your operating system (Windows) will ask for a username (or email address) and a password. This process is called "Windows User Account Control" (UAC).

To continue with the installation, you will need to enter your local Administrator username and password. If you do not know this password, contact your computer administrator to enter the information.

We also offer Upgrade Assurance ("2 Years Upgrades and Support"), which would include those upgrades as well. Upgrade Assurance can get renewed every second year, so this would be the only cost to stay up to date with our latest versions at all times.

You may install your license on two computers, as long as you are the only user.

Additional users require additional licenses.

Just install your licensed version from our download page.

If your license is not valid for our current PDF Annotator Version 9, you will first have to buy an Upgrade, or download your licensed version from our Archive.

The situation:

You have created a document in some application which doesn't support PDF export, and want to convert it to a PDF document?

The solution:

PDF Annotator includes a "Print to PDF Annotator" virtual printer. Using this printer, you can create PDF documents from any third party application. The new PDF document will immediately open in PDF Annotator, so you can start annotating.

Here we have prepared more articles and step-by-step instructions for you.

The situation:

There is no "Print to PDF Annotator" printer, or after printing, nothing happens.

The solution:

Please follow these steps for a clean reinstall of the "Print to PDF Annotator" printer:

• Reboot your computer.
• Download this separate setup for the "Print to PDF Annotator" printer: Print2PDFAnnotatorSetup.exe
• Run Print2PDFAnnotatorSetup.exe by double-clicking it in Windows Explorer.
• Follow the steps through the setup wizard.
• When asked to reboot, allow to reboot your computer once again.
• Make sure to log into Windows again, using the same account you were logged in before.
• The setup will finish the installation after you logged in again.

The situation:

After installing an update, PDF Annotator either...

• displays a "Failed to initialize user language" message, or
• starts up in the wrong language, or
• starts up in a mix of English and German.

The language setting under "Extras, Settings, Preferences, Language" (or "Extras, Settings, Voreinstellungen, Sprache") is unavailable (greyed out).

The solution:

A typical cause for this could be that your antivirus software has blocked access to, or quarantined parts of the PDF Annotator application.

Please follow these steps to reinstall PDF Annotator:

• Uninstall PDF Annotator.
• Re-download the latest PDF Annotator version from our Download page.
• Re-install by running the setup. Keep an eye on your antivirus software to see if it reports anything.

The situation:

When opening a specific document, you get a message about Security Restrictions, and you cannot annotate or perform certain tasks in PDF Annotator.

The solution:

These security restrictions are part of the PDF standard. Restrictions enable document authors to allow or disallow certain tasks, like viewing, printing, commenting or editing their documents.

If the author allowed to print the document, you can create a digital copy of the document, then annotate or edit the copy.

If the file is protected by an owner password, but not by a user password, and you know the owner password, then hold the SHIFT key pressed while selecting File, Open, and you'll be able to enter the owner password. With a correct owner password, there will be no constraints on editing the file.

PDF Annotator respects the copyright holder's decision on what to allow and disallow for a published document. If you created the files on your own, check the preferences of the tools you created them with, and recreate them without denying editing (or with allowing commenting). If you received the files from someone else, contact him/her and ask for an editable edition of the file.

The situation:

When printing from Adobe® Reader®, white boxes are overlaying your original document.

The solution:

In most cases, this problem is caused by outdated printing drivers and has already been fixed by the printer vendors. Check with your printer vendor's website if you have installed the latest printer driver, and update to the latest drivers.

This has also been a known problem with previous versions of Adobe® Reader. If you run an older version, update Adobe® Reader® to the latest version.

The situation:

When viewing a document, which has previously been annotated in PDF Annotator, in Adobe® Reader®, grey boxes are overlaying your original document.

The solution:

Probably, the Show Large Images option in Adobe® Reader® has been disabled. Start Adobe® Reader®, select "Edit, Preferences, Page Display" and make sure the "Show Large Images" option is checked. By default, this option is - and should remain - checked in Adobe® Reader®.

The solution:

In most cases, this problem gets reported when printing to PostScript (PS) printers. Try using an alternative printer driver for the same printer (PCL, for example). Or try printing through Adobe® Reader®, which usually always works.

The solution:

You can hard reset the menus by deleting a registry key:

1. Close PDF Annotator
2. On the Windows start menu, click "Run"
3. Type regedit.exe and click OK
4. Find this key:
   For PDF Annotator 9.x: HKEY_CURRENT_USER\Software\GRAHL\PDFAnnotator\9.0\Toolbars
   For PDF Annotator 8.x: HKEY_CURRENT_USER\Software\GRAHL\PDFAnnotator\8.0\Toolbars
   
5. Right click on the "Toolbars" node and select "Delete"

The situation:

I'm getting a "Missing Required Windows Service: Please ensure that required 'TabletInputService' is running" warning and cannot start PDF Annotator.

The solution:

"TabletInputService" is part of the Windows operating system, and required to run PDF Annotator.

To start this service, and to configure it so that it automatically starts with Windows, please follow these steps:

1. Click the Windows Start button.
2. Type services.msc and hit ENTER.
3. You will probably have to confirm this step if you have administrative rights, or get your Administrator confirming it.
4. Scroll through the list and find "Tablet PC Input Service". Double click it.
5. Click "Start" to start up the service.
6. Set "Startup type" to "Automatic" and close the Properties window with OK.

The situation:

The mouse cursor doesn't look like it should, multiple icons are layered or there is a strange shadow around the cursor.

The solution:

Open "Control Panel -> Mouse Properties -> Pointer Options" and activate "Display pointer trails" and change the trail length to "short".

The situation:

You want to open PDFs from within your web browser in PDF Annotator, but another program opens within the browser.

The solution:

This depends on your browser configuration, and on third party tools installed. For example, Adobe® Reader® installs a browser plugin, and registers itself to display PDF documents within the browser. To disable that, start Adobe® Reader®, go to "Edit, Preferences, Internet" and disable the "Display PDF in browser" option. You will have to restart your browser after that. In PDF Annotator, go to Extras, Settings, Integration, Exlorer and press the "Set as default viewer for PDF documents" button, then OK. The button will be inactive if you have already set PDF Annotator for default. Now, when you navigate to a PDF in your browser, you will get the download prompt like for any downloadable file, instead of the file being displayed in the browser. You can then select "Open" to open the document with PDF Annotator.
