I'm in the middle of setting up an XIR3.1 environment. Meanwhile, back at the ranch, my existing production server (XIR2 sp2) needs to be upgraded to fix some issues. I decided to go ahead with sp4. When I tried to run it I get "Another version of this software is already installed. Installation of this version cannot continue..........".
Do I really have to uninstall the sp2 version to install sp4?
