I need some serious answers.  I am trying to install a printer and keep getting a error message.  Can someone  please help?  My operating system is xp with sp2.  My printer is a hp photosmart 2610. About  3/4 the way of the installation it stops and gives me an error message of error 1935.  An error occurred during installation fo assembly.  "Microsoft.  MSXML2,  publicKey Token= "6bd6b9abf345378f", version= "4.1.0.0", type= "win32", processorArchitecture= "x86"'.  That is the whole error message.  Can anyone give me a clue?
