384066 - Flash does not auto-install properly on Vista

Status: VERIFIED DUPLICATE of bug 352762

(addons.mozilla.org Graveyard :: Plugins, defect)

Description

[Michael Morgan [:morgamic]]

If you uninstall Vista on a 2.0.0.x build then attempt to load a flash site (youtube, for example) the auto-install .xpi fails to install and sends the user to a manual install URL where they have to download the install.exe manually.

This is not a good user experience and we should fix this.  Can someone help debug?  I think this might be a Vista security feature.  It is preventing the manipulation of plugin files, particularly actions defined here in the Flash .xpi Adobe provides:
http://fpdownload.macromedia.com/get/flashplayer/xpi/current/flashplayer-win.xpi

I will attach the XML produced by PFS at the URL attached to the bug (see URL field).
