I can't get the 64 bit version to run on my 64 bit Alienware computer. I keep getting the 0xc0000022 error when I try to launch S3D V4. I've loaded the 32 bit version and it runs just fine. I've searched the internet and tried all the recommended fixes, DLL files, permissions, video drivers, you name it. Nothing works, it just won't start. I've loaded other 64 bit software with no problems in the past and recently. The only other program that has given me the same problem is Itunes 64 bit. I would really lovde to use the 64 bit version and get the most from my computer but I'm at the end of my rope and don't know what else to do. Any help would be greatly appreciated.
