5.1isp1 Project Navigator - "FATAL_ERROR:GuiUtilities:WinApp.c:583:$Revision "


Keywords: iMPACT, ISE, FATAL_ERROR, GuiUtilities, WinApp.c, status

Urgency: Standard

General Description:
Project Navigator fails at seemingly random times, reporting the following error:

"FATAL_ERROR:GuiUtilities:WinApp.c:583:$Revision - This application has discovered an exceptional condition from which it cannot recover. Process will terminate. "

The error can be reported during different design phases, including:
- Adding HDL design files to a project
- Taking a snapshot
- Saving a source file (inside or outside of the ISE software)
- At the end of any process


A problem in the code related to the detection of hierarchy changes causes this error. Any time there is a change in the status of a design source file or process, there is the potential for this problem to occur. The possible manifestation varies by design and is more likely to affect larger hierarchical designs.

This problem is fixed in the latest 5.1i Service Pack, available at:
The first service pack containing the fix is 5.1i Service Pack 2.
