No, I am not.

I fixed the problem. Just add these files to the Bitdefender's exclusion list.

makemkv.exe
makemkvcon64.exe
makemkvcon.exe

It worked after adding mkaemkvcon64.exe so I added the others just to be safe.

I'm using the full version of Bitdefender. I think this is related.

Before I installed Bitdefender I was able to run the program.

I have the same issue and same error message.

Running as Administrator did not help.

I'm curious, what Antivirus are you using?
