I'm trying to resolve some error messages which arise on a friend's Dell Inspiron 1501 lap top (running Vista) on booting up:-

Dell Wireless WLAN Card Wireless Network Tray Applet has stopped working.

EULELauncher.exe has stopped working.

CIL Application (Command Line Interface) has stopped working.

All 3 have a cancel/debug option but the debug option just tells me "no register JIT debugger was specified".

I haven't been able to find anything on the web to help.

I have updated VISTA and removed the McAfee anti virus package but this has no effect.

I have never used Vista before and and completely stumped. I haven't tried to run many programs and cancelling the error messages seems to leave everything running OK (AFAICT).

Any help/advice would be gratefully received.
