Any program you install on a machine has some effect on its operation; it all depends how much free space you have on your hard drive. The data you give seam OK, so go ahead and install the program. But before you install it make sure that your system is thoroughly cleaned. See below for that.

A THOROUGH CLEANUP, WIN XP:
