Error 1327. Invalid Drive:H:\

When I try to install LBP update 1.9.9, I get this message. I do not have a "Drive:H:\" installed. Any thoughts as to what the issue is?? Having the exact same problem with AVCataloger software as well.

I'm not sure where that may be coming from. I suggest a manual uninstall of Logbook Pro from the Windows Control Panel Add/Remove programs area, reboot, install 1.9.9 after downloading the full setup.
