OK, we have an application at work who’s help wasn’t working under Vista SP1.
Had a hunt, found this on the Microsoft web site.
In short, download a patch from here to install the executable.
There are 32bit and 64bit installation packages.
You now need to create the following entries in the registry.
- Create the folder:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WinHelp - Next create the following DWORD (32-bit) values in the above created folder:
AllowProgrammaticMacros with hex value of 1
AllowIntranetAccess with hex value of 1
At this point the PC should be bounced. On starting back up, the old help files should now work fine.
