It isn't as easy as just installing it. You have to go through and deactivate the security settings on the device, then manually download the program from the Adobe site (not the browser add-on) and then once downloaded and installed, you have to reset the security settings. And this is going on the idea that the manufacturer hasn't restricted your ability to do that/add such programs. It could involve rooting the device, which can actually damage the device, and isn't something I can advise on.
