Wow, getting rid of Citrix can be a pretty big pain.  Let's say you have an issue with Citrix but for some reason IMA won't start.  Who knows, maybe you installed a Rollout that killed it, or maybe you tried CHFARM and it killed it (I've managed to kill IMA in some very interesting ways) in any case, IMA wont' work and now you just want to repair, or remove Citrix and start fresh.  Well you can't because IMA needs to be running to remove Citrix.  This is very frustrating because the entire reason you're trying to remove it is because IMA won't run to begin with.  Well here is the quick and simple solution for you:<!--more-->

Download whatever version you have of Citrix and find the mps.msi file.  This is normally located in the Citrix Presentation Server directory.  After you find this open up a command line and get into the directory that has that file, from within that directory run this command:

msiexec /x MPS.msi CTX_MF_FORCE_SUBSYSTEM_UNINSTALL=YES

Die Citrix Die!  :-) This will destroy Citrix regardless that IMA isn't working.  And the good news is you already have the installer downloaded so now after you get it off the server you can install a fresh new copy.
