Hi,
in your activation request is missing Unique Machine ID. Without this ID the S32DS can't be activated. Your very first attempt on different PC machine contains such ID and the activation was ok.
The Missing machine UID often occurs when you are using Virtual Machine. In some cases the OS security policy block S32SD to obtain such ID from OS. You can try to backup content of c:\ProgramData\FLEXnet\ folder, delete it and try the installation again.
