Adobe acrobat 9 - How to update?

[EmmEmm]

Hey guys

New to this forum thing as do not post often.  But i have a pdf that has video in it and t say to open the pdf in Adobe Acrobat 9 or Adobe reader 9 to view it.

I believe i have Adobe acrobat professional 8.0.0 via CS5 suite on my mac / operating on El Capitan.  Can anyone tell me:

1) Is there a one off way to to read this PDF in a online version of Acrobat 9, so i dont need to download another piece of software and take up more space, as i dot believe i use it much.

2) If NO to the first answer, ho do i go about upgrading to the latest version so i can get Acrobat 9 on my system?

Thanks again

acrobat 8 cannot be updated to acrobat 9.  it can be updated to the last acrobat 8 version.

acrobat 9 is no longer sold by adobe and acrobat 8 is too old to be used to upgrade to the current versions (sold by adobe).

you can buy or subscribe to the latest acrobat versions.

to buy: Adobe products: desktop, web, and mobile applications | Adobe

to subscribe, Plans and pricing | Adobe Acrobat DC

Just open your PDF with the latest free Acrobat Reader DC which runs fine on El Capitan: Adobe Acrobat Reader DC Install for all versions

And be sure to have the Flash Player installed (for the video).

You should update your Acrobat Pro to 8.3.1, it's free.
