+Since you are using Microsoft Windows, you will need the 'nmake' utility
+before installation. It's available at:
+
+  http://download.microsoft.com/download/vc15/Patch/1.52/W95/EN-US/Nmake15.exe
+      or
+  ftp://ftp.microsoft.com/Softlib/MSLFILES/Nmake15.exe
+
+Please download the file manually, save it to a directory in %PATH% (e.g.
+C:\WINDOWS\COMMAND\), then launch the MS-DOS command line shell, "cd" to
+that directory, and run "Nmake15.exe" from there; that will create the
+'nmake.exe' file needed by this module.
+
+You may then resume the installation process described in README.
