If you really care, then author a (type 51) custom action that sets ALLUSERS to 1 so that it doesn't matter if it gets specified on the command line.
ALLUSERS=2 is often not what you want because it simply backs off to a per-user install if the user doesn't have enough privilege. Phil Wilson -----Original Message----- From: Paul Baker [mailto:paulbak...@gmail.com] Sent: Sunday, March 07, 2010 9:14 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Ensuring an MSI can only be installed per-machine I have set the Package/@InstallScope attribute in my WiX source file to "perMachine". 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.
