Missing HEVC-codec when rendering video in premiere (25.5)

When rendering video from drone footage (Codec: MPEG-H Part2/HEVC (H.265) (hvc1)) I get the error "Failed to install the following item: C:\users\publicx\documents\AdobeInstalledCodecsTier2\4.3\mc_enc_hevc.dll". "Close your other applications, make sure you have write access to this location and that there is enough free space on your hard drive. Alternatively, try deleting the folder C:\users\publicx\documents\AdobeInstalledCodecsTier2 and restarting the application."

 

When I then click OK, I get the following message: "This file requires the HEVC codec, which is included with a Creative Cloud membership. To upgrade to a paid membership, go to  

 

I've checked everything, and I have write access to the locations. There's also more than enough disk space. In fact, last weekend there were no problems with these files in the same version of Adobe Premiere (25.5) and Adobe Media Encoder (25.6). I also have a Creative Cloud membership. It's a subscription every year.

 

There's one odd thing. I'm rendering with an enabled NVIDIA Geforce RTX 4070 Ti card when the error occurs. I've also disabled the Intel graphics adapter on the motherboard (MAG Z890 TOMAHAWK WIFI (MS-7E32)). When I enable the motherboard's graphics adapter, the video renders, but much slower.

 

I work on windows 11 pc

@Leontine1994,

 

See this thread and the correct solution:

https://community.adobe.com/t5/premiere-pro-discussions/unable-to-install-mc-enc-hevc-dll-for-hevc-decoding-encoding/td-p/13590930

 

This issue has occurred over several years, and there does not appear to me to be a reliable solution. Adobe installs its own versions of the hevc encoder/decoder, and it is DIFFERENT for various PR versions. The directory and the file versions themselves must match.

 

For example, I think the PR 25 path on Windows is:

C:\Users\Public\Documents\AdobeInstalledCodecsTier2\4.3

 

Some of the occasional fixes appear to be related to permissions.

I've done everything RyanShepard described in the link. I haven't created a new administrator account yet. But I've combined the drivers from my laptop, which I sometimes use for editing, to my desktop, and that works. I just get the following message: "Cannot delete: C:\users\public\documents\AdobeInstalledCodecsTier2\4.3\mc_enc_hevc.dll." "The old version is being used until this file is updated. To update this file, close your other applications and check if you have access to this location. Or try deleting the C:\users\public\documents\AdobeInstalledCodecsTier2 card and restarting the application." If I click away this message, rendering continues normally and there are no further problems. I will definitely also test whether creating a new administrator account has any effect. Ik let you know

@Leontine1994,

 

Thanks for reporting back. I don't recall that message being reported before. Interesting that it works like that.

 

Let us know what you find.

I don't use HEVC but I do have Win11 and a couple days ago there was a Windows update... if you have updated Windows you MAY need to reinstall the codec

reinstall the codec

Premiere Pro does not use the MS codec, it has its own.

The same goes for the new Elements.
