I hate asking for help, but I am stuck because Creative Cloud is stuck! I get error 81, another installer is running. On Win 10, I have stopped everything in task manager that mentions Adobe, then restarted. problem persists. I downloaded creative_cloud_uninstaller and the exe file gives me the same issue with either the repair or uninstall option. Control Panel>All Items> programs and Features will not repair or uninstall Creative cloud. Any help greatly appreciated
Did you restart your computer?
Have you tried booting up in SafeMode?
Are you logged-in with a computer user profile that has administrative privileges?
yes, no, and yes
So I looked up how to start in safe mode - not something I do every day - and did that. The repair mode of creative_cloud_uninstaller then worked and I am now back in business. Thank you! Now I just wish I understood why all that was necessary.
If it worked in SafeMode, that tells me there's a conflict with some other software or background process. It could be almost anything from your anti-virus & firewall to OS updates. At any rate, I'm glad it worked for you 🙂
Please close all Adobe processes and then rename PDApp folder.
