Installing Flash Player Plugin on Firefox without having Administrator Access or Premissions

Last updated on Mon, 2012-07-16 09:14. Originally submitted by fabio on 2007-02-19 16:32.

UPDATE: The following guide, originally written for Firefox 2, has been used successfully on Firefox 3, 3.5, 3.6, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Users of Firefox Portable edition (same versions) also have been successful using this guide.

The Windows computers available at my University permits login only by autenticated users (students) who don't have Administrator access and permissions.

Installing software on those PC is then not possible.

Recently they finally installed Firefox 2 but without the Flash plugins, which is absolutly useful/needed.

I then tryed to install the Flash Player using the "standard" way (click on the missing plugin link then install the plugin..). However without administrator plugins it was not possible to install.

Then I started doing some tests trying to install the plugin manually. Now I have it installed and working perfectly!

This is how I managed to install it without administrator permissions:

  1. Download this ZIP archive to your hard disk.
  2. Extract the file in the archive. You can use any program capable of opening .zip files (WinZip, WinRAR or the free and great 7-zip). There are also websites which can uncompress archives:
  3. Copy the file NPSWF32.dll to %APPDATA%\Mozilla\Plugins\
    • %APPDATA% is not a real folder. It's an alias. By inserting it in your windows explorer address bar, you'll be redirected to the real folder which holds your applications profiles and settings. The location of this folder depends on various setting that's why we need the alias and not an absolute path.
    • You can open this folder simply choosing "Start → Run → Type in %APPDATA% → OK".
    • In case you don't have a Plugins folder you can create one and place your files there.
  4. Restart Firefox
  5. Enjoy your flash websites!

Well, I remember not being able to install it when I first received my school owned laptop. However, somehow it got updated and now the plug ins are (or were) installed.


But just today, all of the sudden, I can't view videos or any other flash. So I tried to re-install the plug ins and now it's blocked, or I need Admin's permission. -_-

I'll try what you said.

Can you download Shockwave with this method too? I did read the previous post about shockwave download but it doesn't seem to work - I can't find the install.exe thing

Can't Do it!!!

Strangely, my Mozilla folder doesn't have a 'plugin' folder. Would it work if I made one?


how about divx plugin?

how about integrate the divx plugin?

you can try this..

Submitted by fabio on Thu, 2007-12-20 17:47.

I think video codecs (as the divx plugin you are talking about) should be provided by windows only as libraries.. so I don't think the user is able to install them locally.

Probably the best workaround is copying on your windows home folder a video player which is able to play different video formats out of the box (it doesn't need any plugin installed on the operating system) but does not require installation.

You might want to try VLC - Video Lan Client. The version you have to get is the "Windows zip package" available from the VLC download page.

Once you get the above version, uncompress it, launch the application and try to display your videos.

Please note that I can't verify that the above method works correctly (I don't have access to any restricted Win computer at the moment).

Hope this helps.

Forgot to add that the described procedure can be also used to install the Flash plugin for Firefox on a portable installation of Firefox.

A portable installation is an install which is able to run Firefox from an USB pen on every computer you connect the pen.

Personally I never tried the portable installation but people above commented that they where successful in doing this.

The article describe how to install the Flash plugin, a component used to display multimedia contents on web pages, for the Firefox web browser in a restricted environment eg: at work or university where you don't have access permissions to install programs on the computers..

With the procedure described you should be able to install the component and use it in such a restricted environment..

Hope this helps..

neat trick!

If the video you are trying

Submitted by fabio on Wed, 2007-11-14 17:14.

If the video you are trying to play are streaming using Flash, the videos should plays without problems. If the videos are Flash based but you still can't display them it could be a problem on your network or the server (eg: a proxy which restricts loading those videos).

In order to check that the videos are flash based just right click on them.. if you see flash stuff on the menu which will pop up then that is a flash video.

Instead if the video you are trying to display is a quicktime video or a windows media player video you might have a missing codec.

You might post here the link to the video you are trying to play.. I can have a look at it.. just to check it works...

Thanks for the great topic.

Can someone please let me know if there is a way to do the same thing in IE?

Here's my situation:

I have created a Xcelsius application and the data gets imported from Excel and Access DB. I have made all the charts and it works fine, but when I install it on my client machine (government facility), the export as html and powerpoint doesn't let the interactive flash output show up and run because their machine don't have flash player installed. I do not havea dmin previledges, and the only option I am aware of, is to ask their admin to install flash player on every machine there so my application runs. It's a bit of hassle and usually takes a long time for them to do that.

So I was wondering if there is another way around that, like there is some type of code I can add somewhere in my application to embed flash viewer so that my application can pass the firewall.

Thanks in advance!

Can't install Limewire w/o admin priveleges

Unfortunately I don't have experience installing LimeWire in a restricted environment.

Btw.. I doubt that once installed it will work.
Usually at University or at Work this kind of programs are disabled by firewalls or proxy. So.. there are good possibilities that, even if you are able to install the program, then you will not be able to download anything.

How to install Shockwave without administrator rights

Submitted by Mikael (not verified) on Fri, 2007-07-06 10:08.

* Download the install .exe
* Extract it using unpacking software i.e WinRar(Shareware) or TugZIP (freeware).
* copy files to firefox plugin-directory, no subdir just dump them in the plugin-dir.
* restart firefox

I tried it with a random shockwavegame from:
and it worked.

I had problems with my favorite, Iron Stomach, though:

maybe that it is a question of explorer vs. firefox issue in the code of the Iron Stomach page since it is quite old (that is in the days when explorer ruled!)

Hi, thanks a lot
it worked with mozilla. I tried doing the same with opera, but was unable to. Can you tell me the path where operan looks for flash, so that i can copy the files there and get flash working in opera also.


theres an easier way

Submitted by V12 (not verified) on Wed, 2007-05-23 15:16.

I currently have opera, winrar, firefox, and a burning sand game installed on my limited account at the school.

What you need to do is when the program asks you for a customized install path , install the program to C:\Documents and Settings\(your account)\My Documents

afterwards the program works just great :D

probably not so easy

Submitted by fabio on Thu, 2007-05-24 00:18.

I think that there could be some scenarios where your solutions will not work.

My approach is actually a bit cleaner as some organizations explicitly says that it's forbidden to install applications on the personal space.

I have write access, so it was as simple as dragging the XPI into firefox, which prompted to install. Flash controls work beautifully, but for some reason it doesn't show up in the Add-Ons control.

Also, you wouldn't happen to know if there's a way to install java in a similar manner (either XPI or copying plugins, as that worked too)? Thanks again.

Submitted by fabio on Mon, 2007-05-07 22:22.

I think that in your situation portable Firefox is probably the best solution.

However, if you are able to define settings on your Firefox install (e.g. you are able to define bookmarks and homepage), then you probably have read and write access to your Profile folder. It's just a matter of finding it and put the files in it.

I'm sorry that I can't help you more.

On the computers here, attempting to bring up the run dialogue (which has been blanked from the start menu and task manager, and the Windows Key-R combo doesn't work) brings up an error about "restrictions placed on this computer"....

Opening My Computer shows no local drive (we're all on roaming profiles). Do you suggest I use portable Firefox to install Flash, or is there some other way? Thanks.
