installed winxp with 4 accounts

i installed 4 users on my friends computer...with 3 of them being administrator accounts, and one being limited.
with one of the admin accounts, i installed the spyware and what not on there and thought it would go across into the other accounts, but whenever i try to open ad-aware or ccleaner i get missing file errors...
is there a proper way to install programs like the spyware and others so that everyone gets access without any errors?
thanks.

 

more specifically CCleaner isn't working on the limited account...
