I am logged in as a non-admin user. I right click on setup.exe and select "Run As..." from the menu and log in using my admin name and password.

Below a partial log I received.

Action start 15:17:32: ISStartup.
MSI (c) (88:DC): Creating MSIHANDLE (2) of type 790542 for thread 1500

Action ended 15:17:35: ISMsiServerStartup. Return value 1603.
Action ended 15:17:35: ISStartup. Return value 3.

Looking through previous posts, I learned that this was due to some DCOM settings.

I checked on my machine and the "InstallShield InstallDriver" Identity is set to "the interactive user" instead of "the launching user".

In order to try to fix this I installed ISScript.msi while logged in as admin and set up all of the appropriate DCOM settings. I then logged out and logged back in as a non-admin and retried the steps above.

What I noticed is that before running setup.exe using "Run As..." the DCOM settings were set to "the launching user" and immediately after I got the failure above, the settings were back to "the interactive user".

I can only assume that when ISScrtipt starts up it resets the DCOM settings for "InstallShield InstallDriver" back to its default.

Has anyone else had this happen?:confused:

I must also say that all other install paths have no problems whatsoever with DCOM. Its only when I am logged in as a non-admin, and use the "Run As..." feature on WinXP Pro.
