µVISION: Errors Launching User Programs

Information in this article applies to:

  • µVision Version 2.05


I've configured my project to launch a user program. I'm doing this in the Project - Options - Output Dialog. The exact program I'm trying to start is:

C:\Program Files\Internet Explorer\IEXPLORE.EXE

When I compile my program, I receive the following error message:

--- Error: can't execute
  ' "C:\keil\UV2\KSPAWN.exe" C:\Program Files\Internet Explorer\IEXPLORE.EXE'

I receive similar error messages when I try to launch other programs. What's going on?


This error message is caused because of the space in the path name.


Enclose the path specified for the User Program in quotes:

"C:\Program Files\Internet Explorer\IEXPLORE.EXE"

You may specify parameters for programs enclosed within quotes, however, the parameters must appear outside the quotes.
