Ursula, I have the same problem, but it started after a recent JAVA upgrade. I'm not sure which upgrade, but it was prior to 1.6.0_06.
1) Software cannot be installed under limited accounts.
2) You are totally right about limited accounts and accessing the internet thru them.

What I typically do is install software as an admin, then login as a limited user to access the internet and run applications - much safer. But ever since a recent java update, LIMEWIRE can't access the JRE even though running java -version in a cmd window states the version listed above.
Screwy....


Any help out there?
