This problem didn't exist for me not even a week ago, but suddenly did when I tried to launch Premiere Pro yesterday. When I try to launch Premiere Pro (14.9), the launcher freezes indefinitely on the step "Loading importerquicktime.prm". I can't even end the task through Task Manager when it starts Not Responding, I have to restart or shut down my laptop (Windows 10.0.19042).
I've tried a number of things to resolve this issue, including uninstalling and reinstalling Premiere Pro, Creative Cloud itself, resetting OneDrive (where my AppData file is), changing folder access settings in Windows Security, and other remedies people have listed on forums, but to no avail. I don't want to have to reinstall Windows if I don't have to, but I can't think of other options. The only Windows updates on my device since being able to launch the app last (2/15/21) have been Windows Defender Antivirus and an update to remove Adobe Flash Player (2/19/21).
Anyone have any sure fire ways to fix this? Incredibly frustrating, thanks in advance.
Before attempting to reinstall Windows, Premiere, or Creative Cloud?
if you go to the link, I think it makes things pretty clear. I'd say both the creative cloud app and Premiere
This is good advice. There is no good way to kill this bug. If the Adobe Cleaner and a reinstall of Creative Cloud and the applicaton will not work, then you may need to prep for reinstalling the OS. No one wants to go that far, for sure. That said, we always have to be prepared to do such a thing when needed.
The best QEs that I have worked with (typically, those have a past as editors or AEs) at Apple and Adobe always have a full bootable backup of their most recent OS. Carbon Copy Cloner is pretty popular with that crowd. Periodic backups of project files to other drives was also done. I assume that these days, the files are saved to a share on the Cloud.
Unfortunately it seems I'll have to go the route of reinstalling, as a cleanup of CC and Premiere didn't fix the issue. Majorly disappointing that software of this caliber can contain a bug that requires a full OS reinstall to ~potentially~ fix.
It seems that a Windows reinstall did the trick - better than nothing!
