I got the same problem. I'm going to try to make sure the old stuff is removed.
However here is my info
Windows 7 Ultimate 64-bit
AMD Phenom II X4 955 Processor(4cpus's), ~3.2Ghz
Memory 8192MB RAM
DX: 11
Construct2 Install: 32-bit version
I install 32bit and put it on my USB. So I know other computers I might go to may be 32bit.
