Well Your missing out on some good software IMHO.
It reminds me off "xx company are rubbish" But there one of the few who say that.
I only install (if anything) what i am going to use. So i would not (because i have no use for it) install accounting software.
I have downloaded and installed many programs from CD's, since (whenever it was) and now have my collection that i always have installed because they are all of use to me.
I have a trick which i have only just started doing. I'm using Windows XP with two 120GB HDD's. On a little 5GB partition i have a second install of XP. So any software i'm thinking of using or just want to see what its all about i install on the second install of XP. I have yet to come across any software that has messed up my computer.
HOWEVER! There was one jv16 powertools - Never again.
Trial, demo etc etc. I recenly installed NSW2003 and well didnt like it. So i uninstalled it... But on the second install of XP.
Anyway back to the problem... Close down all background programs and try again.
