770, thanks. I'll leave it as 775 whilst I continue testing.
FYI... I think setting
destNofop=1 within
_scriptInstall is preventing these log files from being created. Cleared pbpk and ran a couple of installers with and without this entry and so far it holds up.
I wonder if there's also an entry for setting initial permissions? destProtect maybe?
I figure there must also be a setting to auto-delete the installer on completion.
Seems like the .fop files contain a log of the files installed and the .inf is a copy of the _scriptInstall parameters.
I've updated the installer above to now uninstall. Seems to work. Also added nofop line.
