I can't open pdf's. I have Adobe Flash Player ActiveX and Adobe Reader.
I've tried unstalling them to reinstall; but it won't let me . A box that says: close all internet applications....keeps popping up. I don't have my internet open! But it says I have to close. I just want to be able to open my pdf's!
I now see that you already have Adobe Reader. What exactly means "can't"? Are these local or online documents? If online, in what browser?
Regarding the request to close Internet Explorer see How to close Internet Explorer and other programs running on Windows?
