Installation of SR2013 fails with fatal error.

Hi,

I'm installing System Recovery 2013 Trial on a Win 7 x64 desktop and the installation fails with this message:

FATAL ERROR: Error 1327.Invalid Drive: Z:\ 

I had several SMB shares mounted and mapped to drive letters on this machine before I started the first installation attempt. All were working fine. I have since disconnected all of them, including Drive Z: and rebooted the disktop AFTER disconneecting the drives.

The error persists, and I am still uinable to install.

I am running the installation using a local account with administrator privileges.

Thanks in advance,

Tony.
