The demo download link doesn't seem to be working for me, so I have no reliable way of testing if CKII will work on my computer. I checked the system requirements and I think it should work- the game needs 2GB RAM to run and my computer says it has 3.80 usable. My processor is an Intel Core i3 CPU, and I think my graphics card is something like an Intel HD (I might be confusing something though).
If that information doesn't help... I could run the original CK with no problems, but I can't run EUIII. Sorry if this information is a bit unclear; I wasn't quite sure where to look. Thanks in advance for any help.
