I tried uninstalling a game and reinstalling it again and ran into a problem

Ok, first download CCleaner, from here > http://www.piriform.com/ccleaner/download <.
After installing it, you will have 4 tabs, click the cleaner tab and select all the boxes,except the last one, and a couple you dont want to, ie user assist. After running that, go to the registry tab and fix all issues.

I run into a similar problem. I just threw a whole Ubisoft folder into the trash and now when I want to reinstall the game an 'already on your system' error come up. Theoretically I downloaded the already mentioned CCleaner, but there are 3 not 4 tabs and I would feel better knowing the names of the boxes I shouldn't touch. I really would not like to screw my system or lose saves from other games. I'm rather green at this, not even sure it is possible, but I don't want t risk it… Also English is not my first language.
Recently I reinstalled the whole system and I would rather not do that again so soon, especially for a single game.
Help.

Same problem

I'm having the same issue. Tried using ccleaner, and it didn't solve it. Any other ideas?

Try reinstalling the Ubisoft game launcher?
