Getting Flash plug-in to work with older CPUs
Version 11 of the Flash plug-in for web browsers has been compiled to use the sse2 feature in the CPU. This was introduced in the Intel Pentium 4, but other chip manufacturers only used it in 64-bit CPUs. If you have a Pentium 3 or earlier, or a 32-bit chip from AMD or VIA, the plug-in will not work. If you have a 32-bit computer and Flash is not working, follow these instructions.
1. Check your CPU by entering this command in a terminal emulator:
If the Flags line doesn’t contain ‘sse2’ (‘sse’ won’t do), then you need to use version 10 of the plug-in.
2. Check that you do have the wrong version. In Firefox, enter the url ‘about:plugins’, in Opera ‘opera:plugins’, or in Chrome ‘chrome://plugins’, and see if Shockwave Flash is version 11.
If (1) and (2) showed that you need to change the plug-in, there’s no need to uninstall and re-install: just changing the plug-in library file is sufficient.
3. First find where the file ‘libflashplayer.so’ is kept. The most likely places are /usr/lib/flash-plugin or /usr/lib/adobe-flashplugin. If it’s not there, look for a nearby folder with the name of you browser’s provider — e.g. for Firefox, that would be /usr/lib/mozilla — and that will contain a symbolic link to libflashplayer.so.
4. Download the Flash package. Currently the address for the last issue of version 10 is
If it’s not there, check at
5. Open the file with your archive manager (or at the command-line if you prefer). Inside is a folder called 10.3.183.20 and inside that is another archive flashplayer_10_3r183_20_linux.tar.gz and inside that is libflashplayer.so. Extract it.
6. Now move it to the correct destination. The command will be
su -c "mv -f Downloads/libflashplayer.so /usr/lib/flash-plugin"
sudo mv -f Downloads/libflashplayer.so /usr/lib/flash-plugin
Obviously use the correct addresses if mine don’t apply.
That’s it: congratulations!
I have found out, that on Pentium III Mobile 1 Ghz I can also use all versions < 11.2.
I currently use version 22.214.171.124, which works fine.
For additional info and discussion see here:
In Linux Mint, the plugin is kept in /opt/mint-flashplugin-11/
oops posted in wrong thread - deleting... well I would if I could figure out how to.
It works for me
Thanks man i have a AMD athlon XP 2400+ & this worked for mee :-)
Addendum to modify the information of post #1
Hmm...it may not be that simple
(Starting to understand why not everyone likes Linux)
Post#1 describes how to replace an existing version of the file libflashplayer.so by an older version. Version 10 of Adobe Flasplayer will work with older CPU's. However the latest version 10 is not the one mentioned in the article.
Actually the most latest version 10 to download from Adobe website.
you can download the file 10.3.183.90_archive.zip
This archive contains a lot of maps and folders for different operating systems.
While making your way through the unzipping process, you can remove all the non-linux related items. Keeping only the unzipped Linux stuff makes your work easier to reach the file which you need.
This file (libflashplayer.so) is the one we use as source to replace the file which does not work for your older system.
Regarding STEP 3, the existing locations found on my system were the following
Computer/usr/lib/flashplugin-installer/libflashplayer.so (17,422,820 bytes)
FIREFOX actually uses the same file, in the samefolder. Please note that the file is accessed via LINKS, appearing at other locations made by Mozilla.
The existing file must be replaced by the older file with same name, which was unpacked.
To do this, finally copy the extracted file libflashplayer.so
to the DESTINATION folder /usr/lib/flashplugin-installer
My SOURCE FILE was :
This Terminal (copy) command overwrites the not-working existing file with the old working version. The COPY command keeps the source file for expected later use (instead of using the move command)
This worked for my old PC with Celeron CPU. However Chromium was removed before executing the procedure, with Firefox only installed. I guess I should install again Chromium, to verify if some links are working now in this browser as well as in Firefox
Thanks for the info
Thanks for the detailed and patient :-) response
had figured this out after posting the query.....yup thts true that why every body does not like linux...
and thats part of the game ...anyway thanks again....
