Hi Rick, Each time I try to select a .net assembly to import I receive an 'Invalid Typelib' error and have to exit out of HelpBuilder. Please help. Thanks, Craig

Sounds like you're missing a dependency. When you import an assembly all dependencies have to be available either in the same folder as the assembly you are loading or in the GAC.

That's an odd error message though - not sure what type library has to do with it.

Could also be a version issue - if you're running pre HB 5.0 the runtime used was .NET 2.0 and it wouldn't be able to load some .NET 4.x assemblies. HB 5.0 uses .NET 4.5 for the import DLL so it can handle any type of assembly to import from. +++ Rick ---

Well, HB working like a champ today... No issues at all. Only change was a reboot after HB install. Thanks, Craig
