A video presentation requires an old Macromedia Flash Plug-in 6.0 version. What to do?

Hi,

I have a video-course that requires an old version (Macromedia Flash Plug-in 6.0).

I know that is a very old version, but I need to study it again, but does not work with the new Flash versions.

What to do?

I already tried with all browsers (Firefox, Explorer, Opera and Chrome).

My version is 15,0,0,189. Windows 8.1 - Intel Celeron - 64bit.

I appreciate any answer.
