Solve : Downloading & Installing .exe files?

1.	Solve : Downloading & Installing .exe files?
Answer» If I download & save software to my external HARDDRIVE, then INSTALL/run the software (.exe file), does it install to my internal harddrive? Can I "run" the software from my external harddrive? I am trying to clean up my 'puter CUZ there's so much junk on it... Can I then remove it from the non-running drive?When you install the software you should be GIVEN an option to choose the location to which you want it installed.
