UncleJey, it would be helpful if you gave us the actual text in the error message. If it's Construct 2's error message and not a Java error message, if you read it carefully it should tell you what to do: visit java.com, find the 64-bit version of Java (by default it gives you the 32-bit one) and install that. It's not a bug, it's just the 64-bit Construct 2 will use 64-bit Java, and by default you only get 32-bit Java installed which is the wrong one.
