Failed to load language 'IronPython 2.6': Could not load file or assembly
Was trying to create a Python macro in a fresh umbraco 4.5.2 .net 3.5 installation and got the following error:
Error occured

Thank's for this information - I'm quite new to Umbraco, but have used Python for about 10 years - even Jython super cool for testing Java classes.
I'm planning to use Python instead of XSLT for all progamming like tasks - very inspired by you and Jonas Eriksson's thread on Python i Umbraco. Python rocks for sure - so the above error was very dissapointing for me and I had no clue about the cause.

Anybody know what that could mean?
While Googling I found this: http://forums.asp.net/p/1598242/4093594.aspx Seems they have the same issue. No solution provided though.
mmmm, it seems the dll was just missing. Any reason why it was left out of 4.5.2? I copied it from 4.5.1 and now it seems to work again.

Now hunting for some dll.....
