Ok, for some reason the Activation screen didn't come up right away. (maybe that's normal). Anyway, the Mem command worked once I saw that screen and followed the rest of the instructions: 1.Make sure you are running the Keygen as administrator and with UAC off on Vista or Windows7 but you have to anyway to install Adesk products. 1.Install Autodesk Autocad 2012 2.Use Serial 69, 68, 45. Or anything matching those templates 3.Use as Product Key 001D1 ( or 235D1 ) 4.Finish the installation & restart Autodesk Product 5.Before clicking on Activate You have 2 options: - a) Disable Your network Card, pull the network cable out or block with firewall (this is just to disable online serial check) OR - b) Click on Activate and it will tell you that your serial is wrong, simply click on close et click on activate again. Choose option a or b. Select I have an activation code from Autodesk 7.Once at the activation screen: start XFORCE Keygen 32bits version if you are installing a 32bits application and 64bits if you are installing a 64bits application.
