I am having a huge issue with Adobe Premiere Pro in which I can't export/render and sometimes even preview files that need HEVC decoding/encoding. I get an error stating that:
Unable to install:
"C:\User\Public\Documents\AdobeInstalledCodecsTier2\4.0\mc_enc_hevc.dll"
![Screenshot_20230217_122500.png Screenshot_20230217_122500.png](https://community.adobe.com/t5/image/serverpage/image-id/503331i1C54AB838EF2C861/image-size/large/is-moderation-mode/true?v=v2&px=999)
It suggests a permission issue, but even if I give the proper permissions to that folder it does not work. Also, the current Windows directory is actually "Public\Public Documents\" NOT "Public\Documents", so I don't know if this is part of the problem.
Most of the time I can edit, but once in a while it will throw the error when editing and my Program preview will fail to display. Restarting Premiere solves this issue until it happens again.
Runing Premiere Pro as an admin or not has no impact.
I have also deleted the "\AdobeInstalledCodecsTier2\4.0" folder and Premiere does recrete the folder, but not the .dll file.
The .dll in question is in the "\AdobeInstalledCodecsTier2\3.0", but if I copy and paste it into the 4.0 directory the .dll will disappear once I launch Premiere Pro.
I have tried uninstalling/reinstalling Premiere and Media Encoder. I've also reinstalled the Windows HEVC codec to see if that helped, it didn't.
I have seen other solutions invloving creating a new admin user, but the steps I found to do that also give me permission errors. I may be doing something wrong or my comptuer is set up differently. Either way, this isn't really an amicable solution even if it could work.
I have successfully opened and exported the same project on a different computer, but I need this to be resolved on THIS computer as it my primary workstation and I will have more projects.
