I downloaded o2ksr1adl.exe from the ms website. When I try to install, everything goes smooth as it appears to be checking my configuration. Then it asks for the Service Pack 1 CD?!?!?!? This is a download! And, it doesn't give me a browse, so that I can point it to the 'o2ksr1adl.exe' file or point it to my cd drive. I NEED TO INSTALL THIS UPDATE. HELP!
