I can't get the new version of WinHelp32.exe for Windows Vista to work without error messages to enable macros. There is a persistent warning message "There was a problem running the macro (1037)". A key in the registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WinHelp is missing. To solve these problems make sure to add a DWORD value that is named AllowProgrammaticMacros to this subkey. If the value for AllowProgrammaticMacros is set to 1, the macros will be turned on. If the value is set to 0, the macros will be turned off. Here is the corrected text for the REG file to fix the Vista version of WinHelp32: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WinHelp] "AllowProgrammaticMacros"=dword:00000001 "AllowIntranetAccess"=dword:00000001 Support Microsoft: The Windows Help (WinHlp32.exe) program is no longer included with Windows Vista
