Nah ur good, I have Daz's readme that tells everything to do, no worries too my memory can get messed up sometimes lol
Update: installed Server 2012 on a seperate new DVD. Succesfully activated. Found the DELL cert and the generic OEM:SLP key. Everything works! Let's goooo! Edit: it did not add all OEM info (only the Model) but I think that is normal for Server 2012 as it obviously doesn't support all the stuff older versions did such as Server 2008 R2 and more
