I have windows XP and firefox is my browser. It continues to say I have
insufficient permission. In the control panel, it shows only user accounts
which I think means I should have permission. Still not working and very
frustrating, will not allow downloan of adobe flash player.
You must run the installer under an Administrator account. Alternatively download the offline installer http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#mai n-pars_header and save it to disk, then right-click on the installer and select Run as Administrator.
If the permission problems persist, check How do I fix Windows permission problems with Flash Player?
