It doesn't work! I have copied the files in the system32 directory, restarted PC, registered them using regsvr32 and it gives me this error when registering: The module "nvcuvid.dll" may not be compatible with the version of Windows you are running. CHeck if the module is compatible with an x86 (32-bit) or x64 (64-bit) version of regsvr32.exe. I have Windows 7 Home Premium. I am trying to use it in CyberLink powerdirector 12 (it worked with 337 version of drivers, and i'm using the same profile). What to do? I am in a hurry!
