I don't really recommend Adobe Acrobat Reader since it is a large file and takes
longer to install compared to Foxit Reader. I strongly recommend
this Foxit Reader because of it is simple, lightweight and does its job as a PDF reader nothing else.
The best way to view your downloads is by using acrobat reader the latest version. Acrobat reader helps in taking version that are not compatible to your system, therefore its easy to read it with other word format.
I also agree that Adobe Acrobat Reader is the best software available to read pdf files. I am using it for more than 2 years and for me its really good. I have used a lot of software to read pdf files, but believe me, Adobe is the best of all.
