ALLUSERS="2" is a valid setting. http://msdn.microsoft.com/en-us/library/aa367559(VS.85).aspx
As Thorsten said on his reply, don't worry too much about locking that type of thing down. If a user is competent enough to mess with your MSI to engineer a per-user installation rather than a per-machine one leave them to their own devices. I'd be surprised to find any sys-admin who'd do per-user installs rather than per-machine & your average user isn't going to know the difference anyway.

As I understand things, this sets the ALLUSERS property to 1. This effectively causes my MSI to default to a per-machine installation, but does not entirely prevent per-user installs since ALLUSERS can be overridden on the command line. -- If I only ever want my installer to be used per-machine, is it recommended that I do something to try and prevent users overriding ALLUSERS? I was investigating exactly what I might do and tried to prevent per-user installations with a launch condition on "ALLUSERS=1". I tried: <Condition Message="...">ALLUSERS=1</Condition> Unfortunately, this had very little effect. Whilst it prevented installation with ALLUSERS="", if ALLUSERS was set to any value, e.g. ALLUSERS=2, the installation was allowed to continue. Also, it seemed that repair and uninstall were allowed to go ahead no matter what the value of ALLUSERS. -- Why did this condition not work as planned? ------------------------------------------------------------------------ ------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
