The MechwarriorOnlineInstaller says I already have the game installed, but I don't. I did delete the game previously, but I erased all the files I could find. Could you tell me how to solve this problem, I really want a game to play other than War Thunder!

try using ccleaner for your registry, failing that do the following.
start->run (windows key->r)
type "regedit" (minus quotes) into the run menu, hit enter
using regedit navigate to HKEY_CURRENT_USER\Software\piranha games
delete the piranha games folder tree in regedit, then try to reinstall MWO and it should work.
let me know how it goes
