PowerCLI: Error 1406. Could not write value InstallPath to key”

I am trying to install the Power CLI on a computer that has recently been installed with Windows 2008 R2 Server.
During the installation, I got an error message saying
Error 1406. Could not write value InstallPath to key.
Has anybody experienced this problem?
