I checked the bug reports and also the documentation and didn't see anything specific to the issue I've found. For example, the help file says: Which doesn't necessarily tell me anything regarding what I am seeing. Here is an example: RegWrite ( "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions" , "Service1" , "REG_SZ" , "NAV" ) Will write to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions (GOOD!)
