Hi, Yes you can make it work.. but it is not worth it. Instead have a look at episerver.marketing modules, found in the nuget feed. You will find the new A/B-Testing module there that is for the future :)

A/B-Testing add-on is future!

Thank you for your replies, Eric and Thach. :)

@Eric: Okay, so it's not recommended to use CMO with the latest versions of EPiServer?

@Thach: Which add-on are your refering to?

Daniel, yes, it is not good to use CMO at all, and the AddOn talking about is this:

There are a couple of reasons why CMO is a dead end for CMS 10. First the problem installing it. You will need a guid, I have one, or you email episerver support to get one. Second is that you need to install things manually in the DB. This is cause of the fact that they do not have an installer for the CMO product anymore. So it is not that easy.

Another bad thing is that it is using silverlight and component art with a messy license system :) And silverlight is a bad choice cause not many have that installed anymore.

So go for the new module instead :)

Good Luck.
