We are running SAS 9.4 and Studio 3.8 desktop installs on Windows 10. For some reason SAS Studio has intermittent launching problems that are only resolved by a restart. In checking event viewer I see an Audit Failure for Studio - specifically "4673: A privileged service was called" when Studio fails to launch. Does anyone have any idea what is causing this failure? I know this may be more of a Windows issue versus SAS but I am thinking that if it were truly an issue with our GPO security settings for Studio I would expect it to never launch. EG 7.4 never has this issue, it is only Studio.
