[IronPython] Visual Studio Tools Startup Error

[Bruce Bromberek]

I had to repair my VS2010 Ultimate install, and now Ironpython does not work.

I get this error message on startup of VS2010:
The 'Microsoft.IronpythonTools.IronpythonToolsPackage,
IronpythonTools, Version 1.0.0.0 .....' package did not load
correctly.

The Activity Log gives me the following lines with IronPython in them.

I've tried uninstalling/reinstalling IronPython 2.7 with no change.  Any ideas?
