When you insert the game into your PC and you get the menu to go to SP, MP, Install, etc I can't install the game because the install option is not there but yet there are no COD UO Files on my PC as I have searched for any through the file scan. It's also nothing to do with my system requirments as I've had it running before. I basically need to install the game without going through that menu. So if anybody knows how to do it please tell me as i'd love to know. Many Thanks, Josh.
The reason this is happening is because there is still a registry entry for UO, and its telling the game its still installed.
You could try deleting the details using regedit, but i dont advise anyone mucking about in the registry unless they really know what they are doing.
There is an eaiser way out of this:
After you have the menu on the screen, exit it. go to 'my computer', and right click on the CODUO (?) cd, and then left click on 'explore'.
You will see a 'setup' (grey) button. Just double click it and follow the on-screen prompts to install it again.
