This error has been seen when the Microsoft redistributable libraries have not been properly installed on the Windows machine.

Re-running the vcredist executables should resolve this issue.

  1. Run both the Visual C++ redistribution executables located at:
    • <installpath>\tps\win32\vcredist_x86.exe (e.g., C:\Xilinx\Vivado\2013.2\tps\win32\vcredist_x86.exe)
    • <installpath>\tps\win64\vcredist_x64.exe (e.g., C:\Xilinx\Vivado\2013.2\tps\win64\vcredist_x64.exe)
  2. Reboot the operating system.
