Adobe Acrobat Pro 10 open files in separate windows Can't change under preference

[SupDuJour]

I just download Acrobat Pro 10 and I can't open up files in separate windows. When I go to preferences, the options are limited. I also don't like that I can't place on two laptops that I own.

Hi there

Hope you are doing well and sorry for the trouble.

Please go to Edit (Win), Adobe Acrobat (Mac) > Preferences > General > Select, 'Open documents as new tab in same window' > Click OK and reboot the computer once. 

Note: Acrobat Pro X is an old EOL application. For more information please check the help page (https://helpx.adobe.com/acrobat/kb/end-of-support-acrobat-x-reader-x.html)

I have Pro version 10.10.20.3851

Preferences > General > Select, 'Open documents as new tab in same window' > Click OK and reboot the computer once. 

Open documents as a new tab does not appear.

The (very old) Acrobat Pro 10 can _only_ open in separate windows. There is no other option. What happens when you try? Can you send a screen shot showing the documents open in the same window?

"I also don't like that I can't place on two laptops that I own. "

No idea what this means, sorry...

Apparently this license Pro 10 can only be used on one laptop and not another one I own.
