ON TRYING TO UPDATE,IT PARTIALLY STARTED THEN AN ERROR WINDOW KEPT APPEARNG>>>>>"FLOATING POINT DIVISION BY ZERO".I uninstalled the program as a result of this.

This is a really nice program. Windows has the problem of not freeing memory after an application is closed. Which usually results in freezing up or the dreaded blue screen. I notice when my Computer starts slowing down I can click on Tweakall 3 and free up memory that speeds up the system and prevent lockups. It works well with Cacheman. another memory Program that will automatically free memory.. but in much smaller increments. This is a must have!!
