I have downloaded ironruby from [IronRuby.net / Get IronRuby](http://www.ironruby.net/Download) and  
unzipped it and moved it to c:\ironruby. I put c:\ironruby\bin in my  
PATH  
variable and when I type igem, iirb or any of the other commands under  
c:\ironruby\bin directory I get the following:

unknown: Method not found: ‘Void  
System.Reflection.Emit.DynamicMethod…ctor(System.String, System.Type,  
System.Type[], Boolean)’. (NoMeth odError)

Please help

Also, do I need to download anything else to use it with #C classes. I  
want  
to download RPoint for Sharepoint administration and don’t know if I  
need  
anything else

[Install.NET](http://Install.NET) 2.0 SP1. (The easiest way to do this might be to install  
.NET 3.5.)

We should probably add the same startup check that IronPython uses.
