humm... same ... not working...

I put the wait switch like this:

runnas /user:domain\clientadm "MsiExec.exe /i \\Appserv\StandardApps\Acdsee\Acdess.msi /quiet" /password:silentadm /tok:Test.tok /wait /allowargs

the msi reports in event viewer, says Product Acdsee - installation operation completed succesfully.... the %ERRORLEVEL% gives a 0

...and still no Acdess has been installed....
