Unable to install mc_enc_hevc.dll

I have tried all solutions found through google and used the adobe cleaner to do a fresh install of premiere, nothing seems to get this DLL to load properly. I do have an active Adobe CC subscription as well.

 

  1. OS: Windows 10

  2. Version: Adobe Premiere Pro Version 15.2.0 (Build 35)

  3. System: 1700x 32gb RAM RTX 3070rakc

  4. Footage form Canon R5: H.265 4:2:2 10-bit UHD 4k @ 59.94fps

Logré reparar el problema. Se soluciona creando otro usuario administrador
en windows. Al activar el nuevo uso de Adobe premiere termina funcionando.

Of all the software packages that I have, Adobe CreativeCloud is the most disappointing, and I've been using Photoshop since version 1.0   I also have this problem and truthfully, IT ISN'T MY PROBLEM TO SOLVE.   If Adobe made automobiles, they would be in the repair shop 100% of the time.   This isn't the Adobe that I used to know.  This is some monstrosity now.  It does not work.

 

This specifically includes Premiere Pro, Photoshop, and Illustrator.  They all suck now. Thanks Adobe.

Gracias Marcelo. La solución funcionó para mí también. Algo está terriblemente mal con este software si uno tiene que crear un nuevo usuario para solucionar un problema. Adobe debería dejar de actuar como si esto no fuera un ERROR, porque lo es.

After a long chat and about an hour of troubleshooting, the Adobe Support person and I solved the issue. It appeared that the "AdobeInstalledCodecsTier2" folder had permissions that were not staying set (we checked the boxes, but they became unchecked on their own). It tells you what the issue is: "make sure you have write access to this location..." The support guy used Command Prompt and the "net user" command to create another administrator user. After that, I could swap to the other Administrator account and launch Premiere Pro. I checked the "AdobeInstalledCodecsTier2" folder for the "mc_enc_hevc.dll" file, and it appeared twice. After this, I transferred back to my primary account, and the files were still there. I launched Premiere and everything worked. Hope this helps.

Yep if you have Microsoft family restrictions. It won't let you install it into the folder. You have to do it on a side that has admin.

I have since updated to the latest version of premiere and did some
hardware changes to my PC and the issue has been resolved. Wish I had
better advice to give. --
