I have a Win XP Home edition. Until recently, I usually run the Search command to find files and folders on my PC, but for some time I have not been able to. I receive an error that "a file that is needed to run Search Companion is missing". After this message my PC attempts to log on to the internet and when I cancel the dialup it shows the animation fgure of the search command but I cannot carry out the search. But when I connect to the net, it brings out the dialogue to make the search.
