I just bought a brand new computer with Vista Ultimate pre-installed.
I also bought Visual Studio 2005 Professional Edition.  I installed
Visual Studio 2005 and got some incompatibility error message near the
end of the install, to which I replied "continue" and the installation
finished.  Then I downloaded and tried to install the SP1 for Vista
patch, but I keep getting this error message:  "The upgrade patch
cannot be installed by the Windows installer service because the
program to be upgraded may be missing, or the upgrade patch may update
a different version of the program.  Verify that the program exists on
your computer ...".

The good news is that I am able to run Visual Studio 2005 and was able
to create a small test application, but I foresee problems down the
road if I don't apply the patch.  Anybody else experience this?

I've also tried the repair utility and I've tried rebooting, but same
the error message appears.
