I upgraded my Surface to Windows 11, and now I can't open PDFs that were previously accessible. The error message I receive states 'Adobe Acrobat Reader could not open ... because it is either not a supported file type or because the file has been damaged.' These files have been used on my machine for over a year stored in OneDrive, and I can open on other devices that are also on Windows 11.
I'm on the latest version of Adobe, and I've run the Repair Installation.
Let me move this to the Acrobat forum for you, which is the appropriate forum for your question.
