Fixing the Xilinx compatibility issue in Windows 8.1

I installed the Xilinx ISE on Windows 8.1 and run the ISE. Unfortunately, Open project and Manage license properties are crashing very badly. I got to know that this happens due to a compatibility issue of Xilinx on Windows 8.1. Finally, I found the you tube video which describes how to fix that problem, thanks to my colleague Manupa Karunarathne.

What I have to do here is that simply changing some .dll files as follows.

First go to C:\Xilinx\14.7\ISE_DS\ISE\lib\nt64 and find the file libPortability.dll and change it to libPortability.dll.orig to keep it as a backup. Then find the file libPortabilityNOSH.dll file at the same location and make a copy of it to the same directory. Change the name of the new copy to libPortability.dll. After that, copy the libPortabilityNOSH.dll to C:\Xilinx\14.7\ISE_DS\common\lib\nt64 as well. A libPortability.dll file can be found in that new location too. Change that also to libPortability.dll.orig first and then change back the newly copied libPortabilityNOSH.dll to libPortability.dll. That’s all.
