How to change back from Max+Plus II to Quartus II

I installed Quartus II, 9.0. When I opened it, I mistakenly selected the MAX+PLUS II., Now, I want to change to Quartus II, but I don't know how to do that....I uninstalled the whole software and reinstalled it. But, by default, the software showed MAX+PLUS II automatically....

Is there any way that I can change from MAX+PLUS II to Quartus II?

Thanks!!
