After changing the 1025 -> 3137 i saved the file, closed ORCA, loaded the MSI on to a vista machine and it installed without any problems. using the wonderful MSDN documentation i located a value that turns ont he impersonation feature, 3137. There are probably a few different values that this can contain. I navigated to the CustomAction package and located an action with a value of 1025.

On the left-hand side a list of editable regions of the MSI are listed. Once installed i opened ORCA and used it to open the MSI package. To fix this I installed a program named ORCA. My installer has a managed custom action that was not getting the Administrative priveleges that the rest of the installer is running under. It doesn't exactly give the option of setting the impersonate settings for CustomActions included in the MSI. The MSI I have been building is built with Visual Studio 2005.

In my case, the MSI package needs to be distributed through SMS. I encountered the same problem a while back and for the most part the only information I could find was to run the installer from a command prompt with administrative priveleges or other work arounds. I'm guessing this is an attribute I attach to my CustomActions class, does anyone have a C# sample of what the attribute looks like? Usually this can be fixed by merely adding the msidbCustomActionTypeNoImpersonate attribute to the CustomActions. these MSI files fail because the CustomActions attempt to do something that requires administrator privileges. Could someone point me to the correct place where I could set this? However, I don't know how to set bit 3 of the Word Count Summary property to 1. We use VisualStudio 2005 to create our installer, and I'm guessing that ALLUSERS = '' can be set by specifying InstallAllUsers=False in the Deployment Project Properties window. To specify that a package is a per-user installation that can be installed by a standard user, set ALLUSERS='' or don't define the property, and set bit 3 of the Word Count Summary property to 1. To specify that a package can only be installed by an administrator into the Public profile, set ALLUSERS='1' or ALLUSERS='2' and set bit 3 of the Word Count Summary property to 0.
