Trying to install Vegas Movie studio HD platinum 11 on my new Windows 11 computer but with registering I get the answer that my computer ID is incorrect...?
That’s frustrating. Try copying the Computer ID directly, running the installer as admin, or using compatibility mode. If it still fails, best bet is to reach out to support with your license info.
The computer ID is generated by the activation process, not the computer ID located in your PC'S Windows computer data display. That's what I found anyway to successfully register a Sony era software.
Which computer ID are you using in the registration process?
True. I did have some problem as I linked above. But I just tested the procedure with reinstalling and activating another Sony-era Vegas successfully. But you have to follow the instructions very carefully. If you aren't lucky first, start again (and again... I needed to do that as well.).
