Hi,
I found this thread by having the same issue as @Martin353954258orf. I have the lastest, updated version of Adobe Acrobat. I have the latest, updated version of W11, and think that it may have arisen the issue, as it was working very well until that update. Specific issue is - Whenever I try to open Adobe Acrobat either by clicking the executable icon or by double clicking any PDF file, it doesn't open and some minutes later I get an error message "Another instance of Adobe Acrobat is open / Buttons Learn More & Close".
Before looking for solutions, I closed all running processes pressing "Windows+Shift+4". Then I uninstalled Adobe Acrobat from Windows. Then I use the AdobeCreativeCloudCleanerTool.exe. Then I restarted the computer and re-installed Adobe Acrobat. Same problem from scratch. The I repeated the steps and finally re-installed Adobe Reader. Problem keeps.
Can anybody share another possible solution?
