Unable to install mc_enc_hevc.dll

[rackerman]

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

[yannr23066990]

this was of great help!

what a shame that such massive bugs are not fixed

[defaultwdbjge2k9m0e]

Hello, the first part of this fix worked for me, I can import the video to Premiere in the new account (PremiereProSolver), but when I return to my original account, it still doesn't work 😕 Why can that be? Thank you in advance

[Lyndon285890790riy]

OMG! Works really great! Thank you!

[alzoxp]

Hi. I have NEVER in my 28 years bothered to login to a forum to thank someone for solving a pressing issue, but this here needs to be said:
THANK. YOU. From the bottom of my heart!
I am currently behind in schedule in a project because of this nonsensical error that appeared. (I was working with Sony vegas before and thought it would be a good idea to start fresh with this new project and boy did I run into issues)

Long story short: Thanks a LOTTTTT for clarifying what the guy above said. I wouldnt have understood how to do it even though he explained it. I watched hours of youtube videos and went through every single thing.

At the end I found these things:
- when I ONLY used MP4 files in my project, exporting worked fine. But as soon as I had .mov files, everything went to hell and this error appeared making me lose hair in real time for hours and hours on end

Converting the files to .mp4 before editing them also worked. HOWEVER there are certain files that HAD to stay in .mov (because apparently, the background is then transparent. Like certain after effect stuff I got from envato elements)

-this mentioned folder "AdobeInstalledCodecsTier2" was empty. Completely. BEFORE applying what you said.
Right after I did what you said (I did a quick export from within the "PremiereProSolver" user though just because I didnt want to wait any additional second to check if it works.
It worked.

After going back to my main windows user, it first did NOT work. Because the project (premiere pro) was still open during that time. I did not log out of the users, I just switched.

However, once I closed premiere pro (after doing everything you said), and opening it again, then exporting worked.

Fun Fact:
I found a shortterm solution to that problem previously which was: I changed the path. From my first internal SSD harddrive to my other one (both are identical and were bought only 1 week apart from another). Somehow this worked. For 2 days.
Until now the error came back and almost took my soul.

TL;DR: The solution above worked! THE ONLY THING that truly worked. No other forum, nor youtube video could help!! THanks a freaking lot! Hope you are alright wherever you are.

[Sebastian34081706c86a]

Edit: Forgot to end a sentence:
The "... .dll" files (2 of them) appeared in the "AdobeInstalledCodecsTier2" folder after apply everything you said and going back to my MAIN user and trying the first export.

I think my initial comment wasnt replied to the right guy. Search for my name if you want to see a thank you @Marc220862260e1e 

You truly saved me. Thank you!

[TheSailingChannel.TV]

Thank youk Marc. This process worked for me. Previously I had spent nearly two hours with Adobe Premiere Pro tech support with the tech controlling my computer. She said the answer to the problem was to to a clean install of all my CC aps, which I let her do. This took another hour or so due to day's slow internet connection. Eventually we got cut off. After the fresh install I tried again and got the same error. Which I had search this forum first.

When I first ran the command above, I got "this group doesn't exist." But when I ran 'net user' there was PremiereProSolver. I logged in to the new admin account and followed the rest of the directoins. After successfully creating a single proxy by dropping an original 4K file into Media Encoder (I selected Prores quarter frame, which creates a 1920x1080 proxy for a 4K file) magically, two heevc files appeared in the 4.0 folder. I then switched back to my regular admin account and created the rest of my proxies starting in Premiere.

If this has not worked for you please do check this, as it was what worked for me:

In short the problem was the windows antivirus blocking the acess, so you just need to manually enable it. Cheers.

I have to thank this user and also Marc220862260e1e this was the only solution after countless hours of trying to troubleshoot this. Thank you thank you thank you.

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.

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

[aa7bq]

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.

[default1j3qujr8y4c9]

This has happened to me today. After years of having it work fine now my software is bricked. I hope someone can tell me a support email or a phone number I can call to get this resolved. I was trying to edit a YouTube video but this has made me highly discouraged. I am to be honest at my wits end over this.

[Kevin-Monahan]

Hi,

Sorry about the frustration. Yes, you can contact support if you are a Creative Cloud customer. Please go to this link: https://helpx.adobe.com/support.html. In the lower right corner is the chat pod. You can request to be connected to the video queue to find our video specialists.

Thanks,
Kevin

It's very simple, just start Premiere as an administrator.
Right-click on the Premiere icon and run as admin.
That what

Sorry

Wrong alarm, it doesn't work.
Where's Adobe help ???

[Kevin-Monahan]

Hey, Rafael,

Sorry, this is a user-to-user forum. You would need to file a bug to get the devs' attention. You can get assisted help from Adobe reps. here. I am here, but I am unfamiliar with this bug as this post is a year and a half old. More info may help us help you. Can you provide it?

Thanks,
Kevin

Didnt work for me

[defaultp43tx7q2gugx]

😱😱😱😱I just came with this annoying bug and not even creating another admin user worked. However, If I open Adobe media encoder, then import the premiere .prproj file it will prompt me which sequence from that project I want to render. Just select all of the ones you need to render, and media enconder will render as if nothing. 

So instead of sending the sequences from premiere to media enconder, import the prproj file into media enconder and select your render sequences. If you need to re render something because of a correction, just go to premiere, fix whatever you need, save it and then reimport into Media enconder for rendering. I haven't been able to actually fix the problem, but this helps me get around quickly and fulfill my delivery dates. 

Hope this helps somebody stuck with this 🙂 👍👍👍
