Thanks Serg008 i know Rx20 series have problems but i will test out on a R420 and see if i get the same error i had with my R720 so thanks for this new link
I activated 2012R2 with it. I don't have a Dell 2016. Been looking but haven't found one. I saw that post and was fearing it would apply to me too. Thanks for the effort!
