Re: [WiX-users] How do I add both a HKLM and a HKCU key to the registry? And THANKS!

For DLL (and EXE) custom actions, the bitness is determined by the action's binary itself, not any marking in the MSI. In the case of DTF, the initial bitness employed will be the bitness of the sfxca.dll packaged by the wrapping action of the DTF build process. I haven't looked at the source code

Good to know for future reference as I have take Blair's good advice and no longer fool with CA's to touch the registry or the event source and do those with wix elements. My only custom action left decodes a des256 string to get credentials for when I create the service and that works well.
