I got an error when installing 2020.07 vxdiag subaru software. SSM4 reported error “License Verification Failed, you cannot install the software”
Change computer date/time to 2021-01-01.
Reinstall SSM3 & SSM4 software again.
Uninstall DST-i and registry keys
Press Start, input ‘regedit’ command, find DST-i and delete it.
It should be ok.
