I too have a windows vista. Most of the old softwares doesnot install that easy. Some updates are there but for some softwares still won't install. Recently i had a problem i.e. windows explorer keeps on re-starting. Only i could do with my comp was open I.E. Finally i was able to solve the issue. I had to go thru a very hard time. I searched the goodle and found many had the same problem. GOOD LUCK
