I've just updated to the new "PA.c Platform 'Next' Pre-Release 4.1", which I know is a test and is expected to have issues. One issue I've found is an error message that displays upon every platform launch. It reads: "The PortableApps.com Updater must be run from the PortableApps.com Platform. It will not function properly when run directly."
I've tried installing the latest update by clicking Manage Apps -> Check For Updates, and also by downloading the full install directly from the PortableApps.com site, but I get this error message on every launch regardless. Anyone have an idea what's gone wrong?
