I'm not totally sure if CE is encoded like Halo for saving wise, but You can try just using the no-cd crack for it at full upgrade and then putting it into the app folder and renaming the Exe to just halo.exe. If that works, then export some registry keys from CE, rename them to the ones in the Reg Files Folder in Data, and then replacing them. Then It would make a CE launcher.
1) I did that so that it won't become a hinderance to the use of your computer because with it windowed you can alt+tab around the computer.2)If your orginal profile is in the default directory of My Games\Halo, it won't load because the Game loading location was changed 2 the one on the Saves Folder. If it is in there, the executable might be corrupt. Please Redownload and try it again3)I admit i havn't updated it recently, but replacing the exe again with the 1.08 halo no-cd crack might fix the problem. Otherwise, maybe just delete the update exe file, which will prevent any updates 2b1af7f3a8
