Have been successfully using Vegas Pro 18 with Windows 10 Pro and even into Windows 11 Pro upgrade last year. Fired up Vegas today and tried to pull up several previous projects. Was presented with this "Hint" window for every one that I tried:
The activation of AAC (MC) failed.
If you are using the program as a guest, please repeat the activation procedure with administrator rights.
Of course that's exactly what I tried. Same error. Uninstalled, reinstalled. Same error.
Ryzen 2600 / NVidia 1080
16 GB Ram
Western Digital WDS100T3X0C-00SJG0 (SSD)
Windows 11 Pro x64 - Ver 21H2 (OS Build 22000.556)
Anyone know what else I could try?
