Recommendation: If you have a valid perpetual license for this version, it is still a capable tool for professional document editing. However, if you are a new user looking for a PDF solution, do not seek out this 2015 version. It is obsolete. You should download the modern Adobe Acrobat Reader (free) or look into Acrobat Pro 2020/2024 (subscription) for security and compatibility reasons.
Adobe ended support for Acrobat 2015 in April 2020. If you are still using it, you are vulnerable to unpatched security flaws. Consider upgrading to Adobe Acrobat Pro DC (subscription) or switching to a free alternative like Foxit Reader or PDF-XChange Editor.
