Does Adobe Reader require AIR?

If I uninstall Adobe AIR, will Adobe Reader still work?

What is Adobe AIR?: https://www.adobe.com/products/air/faq.html

That is like asking “If I remove Microsoft flight-simulator, will Microsoft office still work?”

Although from the same developer, they are two separate products.

Not the same, since AIR is a product Adobe uses to enable many of their other programs (others if not Reader), so it’s not two random programs that just happen to be by the same company.

Or this.

Yes it is the same.
It is not used to enable any of their applications.

Adobe AIR is a cross-operating-system runtime that lets developers combine HTML, JavaScript, Adobe Flash® and Flex technologies, and ActionScript® to deploy rich Internet applications (RIAs) on a broad range of devices including desktop computers, netbooks, tablets, smartphones, and TVs. AIR allows developers to use familiar tools such as Adobe Dreamweaver®, Flash Builder®, Flash Catalyst®, Flash Professional, or any text editor to build their applications and easily deliver a single application installer that works across operating systems.

Point of linking to Sumatra PDF was to offer a valid option if you decided to uninstall Adobe AIR; you could do without Adobe Reader’s periodic security patches and vulnerabilities as well, if you chose to run either Nitro or Sumatra.

Only real way to answer your question to your satisfaction is to uninstall Adobe AIR and see what happens.

I am using Adobe Acrobat Reader DC Version 2015.017.20050 and I don’t even have Adobe Air. Adobe Acrobat Reader DC works perfectly fine.
