I need to run MDT of my new machine. Have installed Inventor 2012 and downloaded the appropriate version of MDT 2009 to suit. Managed to install and get running on Windows 7 64bit. I am now trying to activate. Have tried my serial numbers for original MDT2009, Product Design Suite 2012 and Product Design Suite Ultimate 2014. Online activation tells me the serial number is not valid. All other methods I can find either also tell me the serial number is not valid or describes a method of manually activating that is not relavent to MDT 2009. (ie, request code form)
case 092 55415.
