Comspec and Windows XP

I know this has probably been answered before but I have tryed every availible resource to find a solution to this coding issue. I need to be able to run a program with command line switches which works fine in all operating systems except XP because of the spaces in "C:\Documents and Settings\". I realize that there is supposably a proper way to make it function using different " & ' but despite my best efforts have been unable to get it to work the code is simple


It simply runs and closes without opening anything. Any help is appriciated!
