4.1i Project Navigator - Error: "There is another Xilinx application running that you must exit before running Xilinx ISE"

Description

Keywords: ISE, 4.1i, OS, another, Xilinx, exit, running, Windows, 2000

Urgency: Standard

General Description:
When I launch Project Navigator, the following error is reported:

"There is another Xilinx application running that you must exit before running Xilinx ISE."

Solution

This error occurs after the PC has crashed while Project Navigator is open. The problem is that a registry key created by Project Navigator at start-up does not close.

To fix this problem, delete the following key (or the similar key on your machine that has the name "FirstInstance"):

- Open a command window and open the program "regedit".

- Navigate to: HKEY_USERS\S-1-5-21-1209013574-1542916558-903097961-2243<your key number may vary>\Software\Xilinx\TkWoof.win32\FirstInstance.

- Delete the "FirstInstance" folder.

- Exit "regedit", then open Project Navigator.

This problem is fixed in the latest 4.2i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates
The first service pack containing the fix is 4.2i Service Pack 3.
