Please try to activate again S32DS v2.2. If activation doesn't work, try it again with base version S332DS for ARM v2.2, there was an issue with Update 2.
If activation still fails, try to backup and delete content of c:\ProgramData\FLEXnet\ and start installation again. The folder is hidden by default.
The origin problem was that I try to use a new activation code of other account and it appears the problem you answered.Now I try to use my activation code to register but it still failed--"Software Activation Code is already used on this station for 3 Activated 2.2" . Could you please return my activation code?
