PES Installation failed with error “The supplied password does not match this encryption key’s password”

Password Export Server installation failed after typing password for the .pes file that was generated in the target domain with error

The supplied password does not match this encryption key's password. 
ADMT's Password Migration Filter DLL will not install without a valid encryption key.

As it’s described on http://clintboessen.blogspot.com/2009/10/windows-server-2008-admt-31-pes.html the reason isn’t wrong password for encryption, but insufficient elevated permissions (UAC). So first you need to start cmd.exe with “Run As Administrator” and then run PES installer in the cmd.exe window.
