Depending on what the icon looks like next to it, I would think it looks like an old dos box with the blue border. If so, you might try using the EXPAND command at the COMMAND PROMPT box...that's worked for me a couple of times already.
Type EXPAND and the path to the file.
I did a SEARCH for CMD.EXE first and then dragged a shortcut to it into my QuickLaunch area to make the command prompt box easy to get to.
I am having a problem installing programs I downloaded and installing them on my Windows XP. I think I might have a virus or something. I ran the house call virus scan and it said I was clean. If anyone can help , please let me know.
