I turned on my computer this morning and when it tried to go through to my desktop, I got a series of error messages, including things like "windows\system32\browseui.dll is either not designed to run on Windows or contains an error" and when I tired to open Windows Mail I got "Unable to initialize contacts - 0x8004104E" and also "msoe.dll could not be initialized". Basically, I cannot get into Mail, my desktop is completely blank and if I want to open a document, I have to go through a tortuous process to get there. Any ideas that might help before I head up the road to the lovely, but very expensive, local tech folk?
Download the file from above link. Place onto a floppy or USB drive. Press Ctrl+Alt+Del to access the task manager. From there click File-New Task(Run). Type cmd and press enter. In the command prompt type: copy e:\browseui.dll c:\windows\system32 and press enter.
Failing that, try starting your pc in safe mode (hold F8 down when it starts up) and see if that helps.
If that doesn't work you could do a system restore to the last point the computer worked OK, but not sure how you would do this if you can't access your usual windows menus....
