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

[Sebastián Magrí]

I'm using pyc.py with and a StdLib.dll, and other DLL dependencies. The
clrtype.py file is passed as an extra file to the pyc command.

   $ ipy pyc.py /standalone /target:winexe /out:myapp /main:app.py ...
clrtype.py
