9.1i ISE - Adding source files causes Project Navigator to freeze


Keywords: projnav, freeze, add, reinstall, hang, unresponsive

Adding an existing source file to a project causes Project Navigator to freeze. The only way to shut down ISE 9.1i is from task manager. Reinstalling ISE 9.1i did not solve the problem, even after I installed sp3.

Examining the system environment, I notice that even if I removed all the Xilinx path information from PATH and delete Xilinx environment variable, after rebooting the machine, the PATH and Xilinx variables are still shown in the variable list.

PATH: C:\Xilinx91i\bin\nt; ...
Xilinx: C:\Xilinx91i


Some wrong message are logged in the registration table. You can work around this problem by following the steps below:

1. Uninstall ISE.

2. Open the register editor entry (execute <run> in start menu, and type <regedit>). (IMPORTANT: Please backup your reg info).
Delete 2 items in Register Editor
a. HKEY_CURRENT_USER -> software -> Xilinx -> ISE. Delete the ISE tree.
b. HKEY_LOCAL_MACHINE -> software -> Xilinx-> ISE. Delete the ISE tree.

3. Reboot and reinstall ISE.
