Hi all,

I just wanted to try 0.2.3.0 RC1 on a totally fresh Vista install and right at the end of the install process the installers gives me the error:

"An error occurred during the installation of assembly"

And a whole lot more (see attached screenshot).

Does anyone have any idea on how to solve this? Thanks in advance.

Kees.
