I'll just add (and risk stating the obvious) that if a limited user could actually perform an install that changed areas on the system that are restricted to administrators, then that would be one heck of a security hole. Administrator credentials have to be supplied somewhere, whether it's an "over the shoulder" install or a group policy push to the machine from a server somewhere.

Subject: Re: [WiX-users] Vista Standard User and perMachine install Per-machine is exactly that: all users on that machine. Anything that affects more than the current user is supposed to require admin privileges to accomplish (that is why opening the clock/calendar in the task bar on XP requires admin privileges) as a basic tenant of machine stability (and reducing the impact of viruses and other malware). As a result, all workarounds, in order to maintain basic machine security, require administrative privilege to setup, which means successfully navigating the UAC prompt as part of your installation routine. If you author your application in such a way as to be completely per-user (and not ever need anything that is a protected per-machine resource) you can do pure per-User installations and each installation will be completely independent of all others (as if they were on separate computers). Of course, some things can't be done this way (drivers, services, GAC, native SxS) but most probably software can (in fact, OneClick is based entirely on a per-User model) even though as an industry we aren't used to it. Of course this also means installing your code somewhere other than ProgramFiles. It also means not using the Windows Firewall APIs or other similar things. It also means not installing the MSM version of the native C/C++ libraries. OTOH, if you are not using Windows/Microsoft Update to service your application (and non-MSFT groups that are not distributing drivers currently can't AFAIK) that won't be an issue. It also means that each user that installs your application will have separate copies (but disk space isn't the issue it once was for most users). COM has a per-user variation, and most hosts don't care, so you can even deploy COM (even in Internet Explorer) per-user. .NET can run full trust without being installed to the GAC from a per-user installation as well, and start menu items/desktop icons/quick-launch-bar icons are all available to you from those installations. -----Original Message----- From: warne warne [mailto:warne...@hotmail.com] Sent: Friday, September 11, 2009 12:49 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Vista Standard User and perMachine install Hi there, My setup is a perMachine (ALLUSERS=1) install which I set in the 'Package' element and thats fine. Just wondering then, is there any way to get round vista's UAC for users without admin rights ie 'Standard Users' ? They get the old "You do not have sufficient priviliges etc" message during install. I understand that is entirely by design but, nonetheless, I would still like them to be able to install. I dont want to allow a 'perUser' install for possible upgrade/uninstall problems later on down the road that I read all about. I set InstallPrivileges="limited" in the Package element also but that just gets over the initial setup part. Is there an MSIEXEC command I could use as part of a bootstrap for example? thanks very much, _________________________________________________________________ View your other email accounts from your Hotmail inbox.
