Cubase.exe disappeared after update to 12.0.70

Cubase has disappeared after running the 12.0.70 update. The program is no longer listed in Windows list of installed programs. According to the Activation Manager, Cubase is activated. When running the installer, it says that Cubase is installed. No option to uninstall. What to do?

Anti virus quarantined it maybe? Its happened with applications in the past. Worth checking.
