It isn't just you. :) I bugged this. Several times. It was finally fixed with Exchange 2013 CU3.
I know that this doesn't help you. As I believe I stated in another post, you need the SP, the RU, and the IU in their original locations. And to remove them in order.

Trying to use add/remove gives me an error message telling me to use setup.com. Is it me, or odes Exchange gets really mad when you delete some specific installation files?

If you look at the Exchange Setup Log, it can tell you which IU it's looking for. At this point, you may have a mell of a hess to clean up.

No I don't believe any of those exist Going through several attempts to upgrade this CAS server to SP3, at each step of the way I get stopped due to missing installation files, which oddly I can't even go from SP2 RU0 to SP2 RU1. It consistently dies at "Remove Exchange Files" and "could not remove product with code4934d1ea-be46-48b1-8847-f1af20e892c1. Fatal error during installation, Erro code is 1603" As near as I can tell, it's because this CAS box is missing files that Exchange is expecting to see in C:\Windows\Installer. I've copied files from the other Exchange machines to this one but my thinking is I need the ones they had before they received SP3 for Exchange...

Eventually, you'll need to cleanly remove the server. The only potential issue I can think of is based on whether you have an IU installed. If you do, you'll need to have the media loaded for both the prior SP and UR. From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Dave Lum Sent: Tuesday, September 23, 2014 1:38 PM To: [email protected]<mailto:[email protected]> Subject: [Exchange] CAS server removal We change our CAS server and just about everything is flowing fine through our new CAS server, to the point we're ready to decommission the old one. We can take the old one offline by disabled in the NIC and email still flows as expected. My next step is to decommission the old CAs server by uninstalling Exchange. What is the potential risk at this point if Exchange doesn't cleanly uninstall? I ask because trying to upgrade it to E2K10SP3 errors with the message "Windows installer: the feature you are trying to use is on a resource that is unavailable", and then when I address that I get other errors and as I'm resolving them (keep in mind I am trying to go from E2K10SP2 RU0 to E2K10 SP3), it seems like I need to install some SP2 rollups before leaping to SP3, but I get an error just trying to install SP2 RU1. I'm wondering if I will run into these same issues trying to uninstall Exchange 2010 altogether. Dave
