Error : ImportError: /lib/libc.so.6: version `GLIBC_2.7' not found (required by /tmp/_MEIqVOKZv/libcrypto.so.10)

Fix : This is because you are running the wrong Installer.

Please check your OS version : 

cat /etc/redhat-release

and architecure :

uname -a

If this displays  :  i686 i686 i386  ; you need the 32 bit installer and if it displays :  x86_64 x86_64 x86_64 ; you need the 64 bit Installer.

Now, depending on the OS version, choose the right installer from : http://admin-ahead.com/portal/knowledgebase/19/How-to-install-Advanced-FFmpeg-Installer-version-202.html

You should no longer have any errors.
