The requirement for IE is a little problematical also. :-)

I'm wondering if it may be possible to do this with PInvoke at the C# layer, 
rather than through the internalcall interface?  i.e. declare 
"SHGetFolderPath" as a PInvoke method, and call it directly, returning an 
empty string if "shell32.dll" cannot be found.  The less we need to do at the 
engine level, the better.
