Xilinx Ise 14.7 Windows 10
Step-by-step:
%XILINX%\14.7\ISE_DS\common\bin\nt64\install_drivers.exe and run as admin.windrvr6.sys with a patched version (available from open-source projects like “xc3sprog” or use Zadig tool to force WinUSB for the cable).
Success rate: 70% (cable detection works; iMPACT stable for short sessions).Running ISE 14.7 inside a Windows 7 virtual machine (VMware Workstation or Oracle VirtualBox) eliminates driver issues.
The License Configuration Manager is notorious for crashing on Windows 10 because of its reliance on Internet Explorer components. xilinx ise 14.7 windows 10

Windows 11 has even stricter security (HVCI, VBS). The driver situation is worse. Your only reliable path is the Virtual Machine method (Step 6). The DLL patch works for synthesis and implementation, but the USB driver will fail 100% on standard Windows 11 installations without disabling core security features (not recommended). Step-by-step:
Xilinx ISE (Integrated Synthesis Environment) was the primary design suite for Xilinx FPGAs from the late 1990s until the introduction of Vivado in 2012. Version 14.7, released in 2013, was the last update to support 6-series and earlier architectures. While Vivado supports 7-series and newer devices (Zynq, UltraScale, etc.), it does not support Spartan-6 or Virtex-6. Consequently, engineers maintaining legacy systems must retain access to ISE 14.7.
The simplest fix: do not use the Xilinx cable. Use a Digilent JTAG cable (HS1, HS2, or HS3). Digilent provides a signed xc3sprog or their own Adept drivers that work with ISE 14.7 on Windows 10. Many Spartan-6 boards (like the Nexys 3) have Digilent interfaces built-in. Install ISE 14
