After you download Windows Privacy Tools (WinPT), use the md5sum.exe program (which you can download at to verify the installation package. Place md5sum.exe in the same directory as the WinPT installation file, then open a command prompt. Navigate to the installation directory and type

md5sum.exe winpt-install-1.0rc2.exe

The resulting 32-character MD5 hash should match the hash that appears on the WinPT download Web site. If it doesn't, your installation file is corrupted and you need to download a new copy.
