Install Flash on Firefox Without Admin Rights

October 5, 2009

Did you ever have the problem that while being on a company’s PC you couldn’t install the Flash player plugin for Firefox?

Well now there’s a solution to bypass this administrator lock!

Flash (under Firefox) doesn’t require an installation at all. Sure it comes with an executable, but the only thing it really does is copy two files to your Firefox install directory.

Here is how it goes:

You’ll need to copy these two files:
flashplayer.xpt, NPSWF32.dll

To this direc­tory:
Mozilla Firefox\plugins\

You can do this either by installing Flash on a sep­a­rate com­puter and copy­ing the files over, or by sim­ply extract­ing the nec­es­sary files from the Flash installer and copy­ing them directly. There are a few pro­grams capa­ble of doing this, but to make the process eas­ier I’ve wrapped them into an easy-​​to-​​use pro­gram that can extract files from sev­eral dif­fer­ent types of installer (and other archives). The name of the pro­gram is Uni­ver­sal Extrac­tor, and it can be down­loaded from here:
