I am confused about this processor. I have a V2 computer with this processor and tried to install Windows XP 64. An error message was displayed that it would not install because the processor was not a 64-bit processor. The company that sold the computer advertised it as a 64-bit processor. Could the reason be that it is a mobile processor in a desktop computer? This website states that it is a 32-bit processor or pre-Sempron processor.
