If it was purchased from online download there is a separate file for the PC checkup. It needs to be downloaded and installed on its own. It will also require a differant activation code which should have been emailed with the code for MEP16. If you bought it in the store I don't believe PC Checkup came with the box set.
I bought MEP16 in the store (Best Buy) and the box definately says it comes with PC Check & Tuning 2010 full version. But the ONLY activation numbers I got were for MEP16 & proDAD Adorage 10SE.
Cannot find any PC check or Tuning 2010.
