Hi Markus,
ILSpy loads my assembly dll just fine. As does a C# app. Only ipy.exe
complains about an error.
I think the missing file error is bogus and something else is going on. But
I'm not sure what. Hopefully the below code and output will explain the
situation better than English verbiage. Note that I verify the file actually
exists very earlier in the script!

Hi, Dave,
Do you want to say that ILSpy won't load your assembly.dll, or it won't load
MSVCR80.dll? The latter one is a native DLL, not an assembly, and thus cannot
be loaded by ILSpy.
I re-read the thread, and my current Guess is that the "AddReference" is unable
to find your "assembly.dll".
Did you specify the assembly name correctly? (Case? Without the ".dll" suffix?)
Grüße,
Markus
