Cubase Pro 8 64 Bits Crashes instantly

I was working normally with Cubase Pro 8 32 Bit Version, then i upgrade my hardware and installed the 64 Bits version and it crashes at the double click instant! It does not open at all!
Then i tried to instal 32 Bits version and works just fine!
Don’t know what happens!
Please i need help!

I am experiencing the same thing. However my version is Cubase AI8 Elements. The 32bit version opens but when I try to open the 64 bit version it won’t even start and crashes immediately. Version AI7 32 bit and 64 bit versions work perfectly. Just the 64 bit version of Cubase AI8 does not even open and crashes. I have uninstalled and reinstalled to no success. I have also installed the AI8 elements update to 8.0.30 and this did not correct the problem.

Any suggestions?
