   clr.AddReference("VcClient") should work. If it doesn't, please ask on the mailing list or on StackOverflow, this is not a support forum.

   @filmor this might actually be a bug fixed in #1076 : it is possible, that "VcClient.dll" is either not a .NET DLL, or has wrong processor architecture, or does not have all its dependencies satisfied. In that case current implementation of AddReference always throws FileNotFoundException.

   @lzw-all-in you might try to do

   import clr
   from System.Reflection import Assembly
   Assembly.LoadFrom("D:\\home\\lzw\\VcClient.dll")

   and see what exception you will get.

   NotSupportedException                     Traceback (most recent call last)
   NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.
