[Ironpython-users] Error running standalone exe using clrtype.py if IronPython is not installed

[Jeff Hardy]

It's the sort of error I would expect if there was an assembly version
mismatch, but that usually goes the other way - installed IronPython
breaking embedded/hosted IronPython. Maybe break out fuslogvw and see
which assemblies are being loaded?

As an aside: I'm impressed clrtypes.py works *at all*. I don't think
there are any tests covering it :(
