publishing plug-in on exchange program - which redistributables can I rely on?

I'm working on a Photoshop plug-in for Windows, to be published on exchange.adobe.com.

It looks like I can't provide an installer when my plug-in is shipped.  So how can I make sure that a certain Visual Studio Redistributable will be there?  Can I rely on Photoshop to install one or more redists?  I was reading that the Visual Studio 2015 64 redist is needed by Photoshop - would that be the one I should target to use to?
