Whenever I attempt to launch ISim from the ISE design tools, I get a prolonged "elaboration" message followed with an error as shown below:

"ERROR: The simulation failed to launch for the following reason: Failed to communicate with child process. Please shut down ISim and retry the simulation. If the problem persists, please contact Xilinx support.

Time resolution is 1 fs

Unable to execute live simulation command."

How can I resolve this error?
 

Have you tried opening a webcase with Xilinx? Or at least posting on the xilinx forums...
