I had Audio Studio 10 on a computer that was originally Win 8. However, now it has been upgraded to Win 10. When I tried to move it to a brand new Win 10 cpu, I'm getting a "Need .net version 2 error" and the software wound even start, What's up?
What do you mean by "move"? I assume you are referring to install. Download the final build of SF-10 from the Magix Download Center and have the SF serial number. Alternately you also download from the "Magix Service Center> My Products". In any case, you will likily need your original log-in when initially registered SF-10 with SCS (Sony)
This should also install any OS files that are needed.
