: VirtualBox often conflicts with Windows Hyper-V; disable it in "Turn Windows features on or off."

If you prefer not to use a VM for performance reasons, you can install the version, but you must manually apply a DLL patch : Navigate to \14.7\ISE_DS\ISE\lib\nt64 . Rename libPortability.dll to libPortability.dll.orig .

Log in with your Xilinx account or create a new one to start the download.

Choose a path with no spaces or special characters (e.g., C:\Xilinx ).
