Windows Installer should be requesting elevation when it tries to install your MSI. Have you set InstallPrivileges="elevated" in your Package Element? Is your MSI per-user or per-machine (InstallScope attribute of Package Element sets that). I've only used per-machine packages so if you're trying to author a per-user package you may not be able to if you want to do stuff like register COM objects.
I've never needed any kludges or fixes even with WiX v2.0 or v3.0 on Vista with UAC enabled. If you don't sign your MSI's the UAC prompts will look scary but they should still prompt for elevation.

I am porting an old WiX (3.0) installer from XP to Windows 7. The installer needs to be run as an admin because makes several calls to external programs that need admin privileges (to register COM objects and such). Even when I am logged in as an admin, the calls to these external programs are failing and thus throwing an error at install time in my MSI. If I run an admin console and launch the MSI, these errors do not happen, since I guess I am more of an admin then. Googling around says this is a common problem in Win 7 and Vista and all the fixes seem cludgy (batch files, registry hacks). So my question is how do I get around this and why is this not a huge deal/common problem? It seems that any installer that needs admin privileges in Windows 7 has to go though hoops. Microsoft presumably has created this situation in an effort to increase security. So is there a new workflow I am supposed to be following to get the same thing done? And/or is there a known workaround for this in WiX? ------------------------------------------------------------------------ ------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------ ------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------------ Colocation vs. Managed Hosting A question and answer guide to determining the best fit for your organization - today and in the future. http://p.sf.net/sfu/internap-sfd2d _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
