Windows

Have seen same problem once. I did a repair install, for another reason, and help then worked.

Hope someone has a simpler solution.

Good luck.

Go to task bar properties and remove the start menu item for help and support. Apply it. Then go back and add it again. This worked for me twice and didnt work for me twice- here's to 50%!

have you tried restoring the system registry from a prior system registry backup, this has been known to fix other problems of a similar nature

Hi,
try to stop the service of zone alarm and crestart the computer and check if Help and support works. to do this follow these steps:

1. Start-Run-srvices.msc
2. Select services.msc and right click and select the option Stop.

Check in Administrative Tools, Sevices, and make sure Help and Support is started and set to automatic. It worked for me.

Myself and many of my customers have had this problem. Unfortunately, I've found no single solution. Try this fix: http://www.dougknox.com/xp/utils/fix_windows_xp_help.htm
This checks for missing registry entries. Also try re-registering the help components:
Click Start|Run then type these one at a time
1) C:\WINDOWS\PCHealth\HelpCtr\Binaries\HelpCtr -regserver
2) regsvr32 hhctrl.ocx
