This is a new Dell Precision T5400. It was ordered with WinXP 64bit by mistake, so we upgraded it to Vista 64bit. This error happens with help files from any program, including Microsoft Office products. Here is what I have tried so far with no luck:
Replaced the itss.dll and hhctrl.ocx files from another Vista 64bit machine that does work.
Unregistered and re-registered the following:
Have reinstalled all programs as well as ran repair on them.
I have attempted to install the fix from Microsoft, KB917607-x64. This file will not install as the Windows update tells me it does not apply to the system.
The machine is running SP2 for Vista. We are now to a critical time where the user needs to access the help files. Any suggestions you could give me would be greatly appreciated!! Thanks!
