Description

Installation of the cable completes successfully and checking in the install log or Xinfo I see:

Installing WinDriver6...
 wdreg exepath=C:\Xilinx\13.2\ISE_DS\common\bin\nt64\wdreg.exe.

DriverInstaller->XilinxPC4Driver First State = 4.

Driver installation successful.

However, iMPACT reports that it cannot find the cable and the Jungo driver never appears in device manager. When I check, Windrvr6.sys is not copied to the system32 directory. The driver cannot be manually installed either.

Attempting a manual install using "wdreg -inf C:\Xilinx\13.2\ISE_DS\ISE\bin\nt64windrvr6.inf install" in command line generates the message:

difx_install_preinstall_inf: err a, last event 0, last error 0. ERROR_BAD_ENVIR

What is the issue here; why is the windrvr6 not installed?

Solution

This has been seen on some Windows 7 machines due to an issue with the difxapi.dll file supplied by Jungo. The workaround is to manually install using the -compat option to bypass this. You will need to uninstall and reinstall the cable driver to achieve this.



(1) In a command prompt browse to your C:\Xilinx\13.2\ISE_DS\ISE\bin\nt64 directory on 64-bit installs or C:\Xilinx\13.2\ISE_DS\ISE\bin\nt on 32-bit installs
(2) To uninstall  type the command:  - wdreg -compat -inf %cd%\windrvr6.inf uninstall
(3) To reinstall type the command:  - wdreg -compat -inf %cd%\windrvr6.inf install
