Just got the disc version of JKA today, and forgot about uninstalling my steam version first. I downloaded JA+ and Boba Fett's UU for the disc version and launched it up. Did not work. SO now after uninstalling Steam I came across a problem; could not uninstall disc version. So, fine, I deleted all the files manually of my drives whilst the disc was ejected. Not I try and install, it says "An installation support file could not be installed... Catastrophic failure" and now I do not know what to do. I have tried reinstalling Steam's version but it does not load Multiplayer or Singleplayer, unfortunately.

EDIT: Problem Solved and using the Steam version once more and henceforth.

Search for any remaining jka folders and delete them. I don't know if it could be a registry problem.

Searched all of my drives, deleted all files, such as skins and assets, moved my configs and wanted skins onto USB. Nothing on my computer, other than the disc, that has Jedi Academy, and it is not working :/
