Uninstall Issue

[Trian]

alright a while back i had Knights of the Old Republic installed and when i was done playing it i deleted the folder in the drive instead of using the normal uninstall and now when i try to install it, the game keeps trying to uninstall and it says "ERROR! uninstall has encountered an error and cannon proceed. Please contact technical support." and then all i can do is press OK and thats all i cant reinstall it at all and iv tried going into the Registry to delete it there but it still keeps doing it can anyone help me?

 

Edit: never mind sorry lol i managed to find a way i use a Piriform CCleaner to get it so im able to install it again
