The install probably fails because I did not include regsvr32.exe in with the sidebar files... This is for 2k3 compatibility, the regsvr32.exe from XP will not work on 2k3 and vice versa -Install VAIOXP (SideNote: The VAIO Shell Extention will not show up in XP x64 but there is a trick on how to get this to show... But I forgot how, something about loading a seperate explorere.exe thats located in a seperate folder) - So when installing this manually copy regsvr32.exe from system32 and place it in the same directory as Sidebar.cab and Sidebar.inf - Right Click on Sidebar.inf and select install (error pops up) - Browse to Sidebar.cab and hit Select then OK - Finally copy Sidebar.inf to X:\WINDOWS\inf (make sure to turn on "Show Hidden Files") - Go to Add/Remove Programs in the Sidebar uninstall section hit the Change button (this will register the sidebar DLL and EXE files) - Start the sidebar
