By design, system flash will only override a component flash of the same version iff the component flash is detected as being hosted on a network drive, so I think this is WAI.

perhaps test with --user-data-dir=SOME NETWORK DRIVE

Hey Will, what would be the implications of switching that ordering?  

There seem to be a few issues where people are having problems w/ the component install (e.g. where the Flash .dll is missing from the component user dir) leaving them in a bad state.  If we preference the system install, that would give us/ gCon a relatively simple remediation (i.e. download Flash here...).

If there is no working component install then it will preference the system install. Are you suggesting allowing preference to system install if it's the same version as component?

I believe that is the suggestion. I don't have any objection to this proposal; do you, Will?

Assuming it SGTY, I can land the code if you are busy.

yes, I spoke to laforge yesterday about this and I don't see any objection to making system flash preferred over component flash if the system flash version is same or higher.
