this doesnt seem to work , the error msg is still there , do u have any other clues ? i dont think its a Vaio issue, ive had this one before i formatted my computer , and the msg was gone after the format. but , i changed the computer 1 week ago , and when i installed the sidebar , the msg came back , note that i have RVMupdatePack 2.1.9 and Dotnet 3.0,2.0,1.1 , also WMP11 and IE7 are already integrated with latest Hotfixes. Thanks in advance ricks !
