Problems installing our software on Windows Vista

Our product is installed via an MSI which has been operating just fine under
Windows XP for the past few years. We just started testing on Windows Vista
and we are encountering an installation problem. The problem occurs when
attempting to register an ActiveX EXE during the installation. Unlike DLL's
and OCX's which are registered via RegSrv32.exe, an ActiveX EXE is
registered by runing the executable with the command parameter /RegServer.

For example: c:\folder\location\MyEXE.exe / RegServer

This is the step which is failing within the MSI.

Just for kicks, I tried this from the Windows shell. Sure enough, up pops a
security dialog box :-\. (BTW, this dialog box pops up every single time I
attempt this command. Shouldn't there be an option to mark the executable as
trusted so that I don't have to go through this once I've already indicated
that the command is safe?)

Anyway, how do I get around this for Windows Vista? Is it a matter of
signing our application code so that it will have a higher level of trust
under Windows Vista?

Your installer needs to be running elevated. Custom actions in an installer
under Vista are tricky. See these resources for some more info:

Simplest way is to right mouse click on the msi file and Run as
Administrator.

If there's a subsequent problem in actually running the application
check out the Properties / Compatibility TAB (on the application's exe
file?) and see if setting to XP helps.

Joseph, please let me know if you finally overcame the problem with /
RegServer.
Signing of EXE doesn't help...

No, the advice which I got did not solve the problem at all.

First of all, the installer is running elevated. I get the Vista prompt
screen An unidentified program, etc... Once I click to proceed, the MSI
should be running elevated, no?

But for some unidentified reason, the launch of the executable from within
the MSI is not occurring elevated. The error I get during the install is
"Unexpected error; quitting" which is the same error I get when running
MyExe.exe / RegServer from the Start | Run.

So if the MSI is running elevated, why the @!#$^@^#$% isn't MyExe launched
as elevated from within the MSI?

Hey all you Microsoft gurus. Can't I get some help with a simple question?

Perhaps not in the way you require.

There may be a difference between "pre-elevating" something by
rt-clicking it and running as administrator, and waiting for UAC to
trap something and throw up an elevation prompt.

UAC is the visible part of a larger and deeper compatibility system.

The same system can be preset via rt-click, compatibility properties;
in fact, there's a "run as admin" option there too. Or the
compatibility system can automatically tailor how an app runs if it
pops up a "did that work OK?" dialog when something finishes running.

Try disabling UAC to see if it will install.
