Might I suggest alternatives - simpler, faster
. If you just want the ability to open PDFs and don't care about bells and whistles, Sumatra PDF is an excellent choice. The program's pretty much limited to straightforward PDF viewing, but it's lightning-fast and uses very few system resources.
. Foxit Reader's not quite
as fast or resource-friendly as Sumatra PDF, but it's still incredibly lightweight, and it packs a few features you won't find in Sumatra; namely, PDF-to-speech functionality, the ability to fill out fields and add text to PDFs, and optional integration with the DocuSign service.
Nitro PDF Reader
. The final PDF reader of the bunch opens files slower than the other two options, but makes up for its somewhat pokey performance with a deep feature list-and it's still the equivalent of an Olympic sprinter compared to Adobe Reader's downright sluggish speeds. The free version of Nitro Reader can print (read: convert) virtually any document to a PDF, comes packed with collaboration, creation, and editing tools, and lets you embed your signature into any PDF. That's just the tip of the ice berg, and even better, Nitro PDF Reader dumps nary a watermark on your documents-a rarity amongst free PDF creation tools.
