Halo 2 on XP problem. NICH can install with XP installer again

Q: I have Windows XP and have installed Halo 2 with the XP Installer 0.3 for Halo 2. I also did everything right and so and it was on. But then I deleted it once in the Control Panel, I was not allowed. Actually, you do it with the XP Installer Uninstaller 0.3. I've only done it and unfortunately wrong gemcht manually. Then I have complete with Eusing Registry Cleaner Registry exempt from the Halo 2 and additionally other wan resolved. And then again with the Halo 2 Registry Ceane from 0.3 installer it all matters deleted from the registry that had to do with Halo 2. Only now if I want to reinstall Halo 2 with the XP installer and I go to Custom installation there comes a message: Installation can not be customized, blah blah game already installed. Is not instaled but I deleted the wrong habs so now he reports it wrong even though it is gone. Then there is still Chose Play or Reinstall what it is not so in the installer of Halo 2 Now I can not install it again. Then there is still something of Windows Live account and login to delete or not so I understand the whole. What can I do now? I dormer would I put on new XP so I can reinstall it? Or is there a file somewhere so I can delete the setup of the game (StartUp.exe) the mirror does not report as installed? Those who wish can also have to ask you a few pictures of the problem or something simple.

P.S. you have the game uf XP with the XP installer to install because otherwise, a message comes: CreateProcessTokenW or so because the game is actually installed only on Vista, it's just me install it so after I've deleted it wrong.

A:

Should not be a problem:
Charge you by the Microsoft "Windows Installer Clean Up" (of course freeware), download and run the 40 KB large / small exe.
