John that doesn't necessarily generate a UAC prompt. It will simply check if the user has the permissions necessary to generate a UAC prompt before the MSI installs.
Sachin is your custom action running during the InstallUISequence or InstallExecuteSequence? What is the Execute attribute of the CustomAction? Generally you won't see an elevation prompt until you start the InstallExecuteSequence (as in after you click "Install" on the ProgressDlg) so if it runs before that in the InstallUISequence you probably want to move it if possible (as always check a verbose log). You also probably want it to have Execute="deferred" set as per http://wix.sourceforge.net/manual-wix3/wix_xsd_customaction.htm If it's set to "immediate" or not at all it's likely this is the cause of the problem. This is all assuming your call to GetMsiProperty function really does requires UAC elevation. I haven't looked at this function myself so I'd first check if that is the case before you start trying to change your WiX code as your changes may be unnecessary if the Custom Action itself is the problem.

Hi All, I am trying to fix a bug in an existing Wix MSI code, the MSI fails on Windows 2008 with UAC Enabled, if we disable the UAC the MSI runs fine. During investigation I found, the Wix is calling C++ custom actions those using method GetMsiProperty to retrieve the properties from MSI. The code fails during calling this method if the UAC is enabled. Does it require specific permissions to call this method or something else going wrong? Code fails at: hr = GetMsiProperty(PREREQUISITE1, &pwszCADataPreReq1, &cchDataPreReq1); Appreciate any help on this.
