Tom's Cleanall Utility

I have win98SE and downloaded Tom's CleanAll found here. I put it in my C:/ root directory and clicked on Cleanall.reg and it appeared in my recycle bin. When I select it, I get the message that it needs to be done in DOS mode and it will now go to that. I click continue and it shuts down and a balck screen is there. Nothing happens, for hours. What am I doing wrong? Feeling like an idiot here. Thanks for any help.

Try Fred Langa's and see if you get the same result, I have not had a computer fail with win98 from here so it has to be that your computer is not setup in the normal fashion or your "command" may be corrupt
