I am testing my first installation with Update Service enabled. When I run my installation, I get an "Error 1406 Could not write value to key \Software\Installshield\UpdateService."

The OS is Windows XP, and I am the only user setup for this computer, and have administrator rights. Since this is not with a custom action or other and is with the Update Service, I am not sure what to do to fix this problem. Any ideas and suggestions would be greatly appreciated.

One note, the computer I am installing onto does have Installshield X Epress as well and am not sure if this key was already setup or locked etc and am not sure if I should try this on a different PC which does not have Express installed?
