I have set Microsoft Internet Explorer 11 to my default browser since at first it required to make the sign in with Internet Explorer 111 even that it didn't help and currently I cannot use my product.
I am using Acrobat reader DC Pro 2 very basic functionalities like signing documents and protecting my PDF files with password. and for that currently I do not need running subscription on the cloud.
so my question is how can I use my license with Adobe Acrobat DC pro that I have purchased in 2015
also it is very important to say that I need this software to my running things every day so I would very much appreciate if if I can get an answer soon as possible.
