Is there a eligible upgrade with the old version of Adobe Acrobat 5?

[jmyk007]

Can I ask what is the latest I can upgrade with Adobe Acrobat 5? It seems that Adobe Online cannot get its an update or latest patch. I am wondering if there is an upgrade to Adobe Acrobat 7 or other versions. This may be an old / unsupported version of Adobe Acrobat but I am still seeking for available options without buying a new product. Please advise so that I can also notify my client about this matter. 

Thank you.

Acrobat 5,6,7,8,9 are no longer eligible for upgrades.

Acrobat 5,6,7,8,9,10(X) and 11(XI) are no longer sold.

So your choice is really between a purchase and a subscription of Acrobat DC. Subscription recommended, it includes future upgrades.

On no account upgrade to Acrobat 7. It can no longer be activated, and doesn't work in modern versions of Windows any better than Acrobat 5.
