I found out that the driver for UR22 MkII is installed in programs files x86 instead of installing in the Program files, am i using the Asio64bits? even if it is in X86 Folder. Can someone answer me. 
As I understand it, if you have a 64-bit operating system, then the drivers need to be 64-bit. For Kernel-mode drivers anyway.
It probably just installs both drivers in the x86 folder for simplicity. If you look in the Yamaha folder you will probably see both 32 bit and 64 bit drivers. If your OS is 64 bit you will be using the 64 bit driver.
