Can't install: "There was a problem checking the system for installed items".
description
When starting the installer, I get the message "There was a problem updating dependency items from the Web Platform Installer products catalog. Some dependencies might not currently be available in the Web Platform Installer feed". Then, it fails to detect the programs that I've already installed, and clicking refresh gives me the error "There was a problem checking the system for installed items" and I cannot proceed with the installation.
