I managed to download that BROWSEUL.dll from the internet on another computer anb save it to disk.
Unfortunately, I don't know how to save it to the broken computer, as I only get a blank, icon free screen at start up
Opening in SAFE MODE wouldn't work
I tried CONTROL ALT DELETE to get to the task manager, but don't know really what to do then. If I click run, the computer asks something like 'open file with what ?'
