installation stopped due to "550 Can't change directory to /PowerMessenger/install_pm/<:No such file or directory"
I tried to initiate installation after clicking "index.php". I was in the "Installation Wizard". After clicking "Get Started" bottom, I got an error message "550 Can't change directory to /PowerMessenger/install_pm/<:No such file or directory". I tried such installation on Explorer, Firefox and Chrome. All attempts failed in the same step. Please help.
