v1.0.1

This version requires that either:

• You have .Net Framework v2 installed on your computer. All versions of Windows up to Windows 7 have this, Windows 8 is the first that doesn't. Windows 8 users might be interested in v1.0.2 of ip4.exe instead, as that won't need ip4.exe.config.

or

• You place the ip4.exe.config file in the same directory with ip4.exe. (the file indicates that ip4 is compatible with .Net Framework v4)

If you keep v1.01 of ip4.exe together with ip4.exe.config, then you have a version of the tool that should run on any computer.
