I occasionally run into the following error when I launch processes within Project Navigator. This error causes Project Navigator to shut down:
"This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information."
How can I resolve this error?
In ISE 10.1 Service Pack 2, there was a fix implemented dealing with the way Project Navigator called other ISE GUI applications (Floorplanner, FPGA Editor, XPower Analyzer etc.) The fix, unfortunately introduced a negative side effect that appears to be a random runtime error. The way this issue shows up is that if you run a process that launches an ISE GUI application, one of the next processes that run afterward will fail immediately with a runtime error. Project Navigator will then need to be re-opened and will proceed correctly until another ISE GUI application is launched.
This problem has been fixed in the latest 10.1 Service Pack available at:
The first service pack containing the fix is 10.1 Service Pack 3.
