Adobe PDF Reader COM-Components licensing

Hello there,

i would like to use the adobe pdf reader com components in my application to show pdf files, which is selled to our customers.

So I read a lot about licensing in this forum but my answer is still not clear.

So I explain my steps:

1. I added a Windows Forms UserControl to my Application, then added Adobe PDF Reader Com-Components to the UserControl. (VS 2017)

2. When i perform step 1 , two libraries are automatically added to my project, AcroPDFLib and AxAcroPDFLib.

When I Compile my project now, these two dll's are copied to my Debug/Release folder.

To Run the Appliaction these Two libraries are needed.

I dont't want to deliver Adobe PDF Reader at all, i just want to deliver these two dll's do my customers. If they have Adobe reader installed, fine it will work and pdf files are shown with Adobe Pdf reader, if not installed, a webbrowser control will just offer to download .Pdf files instead of showing them.

Is there any need in this case to license it? The two libraries are useless in case Adobe Reader is not installed, i know, but for my application it will not cause a problem.
