If you are installing under Vista then for a modded version to work you needed to install in C:\Games not C:\Program Files. This gets around various "protection" systems in Vista which prevents the Mod Installation overwriting files. I have no experience of Windows 7 but I guess it works in a similar way if you have been having problems.

Just to summarise the installation sequence:

Install IL2 1946 from DVD
Apply the official patches for 4.08m and 4.09m

Then if you want mods install HSFX 4.1 onto an unmodded 4.09m version.
