The activation of AAC (MC) failed - Vegas Pro 18

@Kauko-Suominen have you checked this thread (in the German forum)?

I've tried all the advice except reinstalling the system, which helped in that case. For some, the problem has returned shortly after reinstalling. The connection of Vegas to Internet Explorer may be an explanatory factor for the problem and there is no definitive solution. Windows updates in some configurations may remove the previously working activation.

I asked Magix to send me an explanation of the Vegas codec activation mechanism so I could look for the reason why it doesn't work, even though I've tried all the ways I could find to fix it except reinstalling the system. I haven't received any answer. At least I wouldn't feel any pangs of conscience if I looked for pirated Vegas now and see if it works on my PC.

How would a pirated version handle the codec activation any better? Doesn't that just break the license check?

Anyway I hope you find a solution or move on as nobody seems to be able to assist.

It is obviously wishful thinking that the activation of the codecs would have been changed as well. The most amazing thing is that nobody seems to have solved this most difficult kind of activation problem except by reinstalling the entire system. Even though the whole other system works except Vegas pro.

How can I open and read Vegas error files .erpt?

It can be register permission problem, see

I wish that person had put that registry key on the forum, when Magix doesn't say it. Magix. Magix stopped contacting me when I asked for more in-depth instructions.

So the comments (and the solution) from user Kwigg in the German language thread I gave a link to did not help in your case?

They didn't help. The only thing I haven't been able to try is the aforementioned connection to the desktop version of Internet Explorer. It no longer works after Microsoft has disabled it. I haven't found any working instructions for restoring IE.

So I, too, have this activation issue on VP14 (yep, and my standard superstable workspace is still VP12). VP14 on a fairly clean machine, and using mobile phone Internet connection instead of network, still no go. I guess this is the end of the road, right?
Where do you go from here, guys? What editor do you use after old VP do not activate anymore?

Did each of you file a support request? Would be good for them to know there are multiple people with this issue and perhaps they have a fix for at least someone?

Kauko-Suominen wrote on 12/6/2023, 1:47 PM

I had a long exchange of messages with Magix. There was no useful advice. It became clear that the activation is tied to Internet Explorer components. Microsoft has killed IE. According to Magix, it should still work. But I think the problem may be related to that. I never received any more in-depth explanation of how the activation works so I could research.

Im having the same issue for a few months now. Really sad that Vegas is now unusable. I tried a lot of things and advices from other threads, as it seems there are more people with that issue.

- uninstalled, reinstalled several times

- Allow software in firewall and defender, also tried with completely deactivated firewall and windows defender

- Starting as adminstrator

- Deleted a bunch of (red) registry entries

- deactivated and reactivated my computer on the vegas account page

- converted the mp4-files via an online-video-converter in other formats and files

- contacted the magix support

- Tried some changes in the internal-settings-tab

Translation of the solution from the German forum of user Kwiqq on 6/29/2021

The solution was to delete one or more Regedit entries.
In my case:
Computer\HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{A807D72D-4267-43fa-8217-07C9FDCDBFF6}

This was not possible with the normal Windows Regeditor, as it claimed the entry was defective. With this program it was possible:
Registrar Registry Manager
https://www.resplendence.com/downloads
As this key alone was not enough, I deleted other keys according to the same pattern within CLSID, which were marked as "unknown" (red) by the program. After that it worked. The defective key came back, when I had the program running and deleted it while it was running, all the plugin activations also worked.

Hope it helps, friends
