[IronPython] Problem loading IronPython on Vista 64

[Matt Channer]

I did try Assembly.LoadFile but this returned null, maybe for the same
reason that I was seeing initially - whatever that is :-)

Fuslogvw now seems to be reporting binding failures (the setting I have is
to Log bind failures to disk).  Interestingly, none of the dlr / ipy
assemblies are being logged here.

I will write a simple test app to see if that exhibits the same problem.

Thanks for the help!

Matt
