I'm running two exchange 2010 servers MX1 sp2( 14.02.0318.001) & MX2 RTM (14.02.0247.005). A month ago is when I installed the RTM then tried upgrading to SP2 it gave me issues and I switched it off. now when I try uninstalling it, it comes as if its upgrading to sp2 instead giving me option to install then gives me the error below.
some controls aren't valid - Exsetup cannot be called directly to perform upgrades. please use setup.com
.
.I removed the Watermark and BulidToUpgrade keys on registry, gave it sometime then the error disappeared but now it was doing an upgrade I don't know from where..then I got another error of services that could not start....Please advise all I need is to remove it then install a package with SP1 that I've downloaded.
