When I try to launch EDK XPS, a command window opens briefly and then closes, and the XPS GUI does not launch.
When starting XPS with the XILINX_EDK environment variable set as a user variable instead of a system variable, EDK XPS does not start. EDK XPS opens the standard DOS prompt and then this closes before XPS GUI has opened.
Make sure that the XILINX_EDK environment variable is set as a system variable.
For information on setting environment variables, see (Xilinx Answer 11630).
