I'm trying to add function that can verify that client has msi.dll with version 3.0 or higher. If it's not 3.0 or higher, display a dialog box that inform the user to download the correct version.
Same function I want to add for checking correct version or .NET.
Perhaps VerGetFileVersion would be a good starting place for msi.dll; for .NET checking the NDP registry key is often preferred, but perhaps you could also use VerGetFileVersion on mscorlib.dll. (If you want to look for a specific version of .NET, don't check the file version; use the registry key, or the Is(DOTNETFRAMEWORKINSTALLED, ...) function.)
