Linux is very different from Windows :
You do not download software for Linux. ( Usually not.)
The 'Package Manager', "Install Software" is used for installs.
( Default : 16,000 entries.)
It's like a catalog, where you just click, what you want,
and it gets installed.
Flash : Make a new entry to your catalog :
> Select version to download...
> > YUM for Linux
.. and download the 4 kB file = adobe-release-i386-1.0-1.noarch.rpm
Next : 1) su , 2) rpm -Uvh adobe-release-i386-1.0-1.noarch.rpm
Now the flash-plugin can be selected in "Install Software"
or installed with the command # yum install flash-plugin
