I have CK1 from AMazon, and in the download folder, I noticed something called EU2_1.08 patch, so I opened it and ran the application inside...It said it was installing EU2, so I was surprised and excited that I seemed to be getting 2 games for one. Once it installs I open it, but there is an error ---- excel file not found.... First, what is that error, and second, why was EU2 seemingly included in CK1?
