Adobe Reader XI 11.0.05

What is Adobe Reader XI?  (from Adobe Systems)

Adobe Reader software is the free trusted standard for reliably viewing, printing, and annotating PDF documents. It’s the only PDF file viewer that can open and interact with all types of PDF content, including forms and multimedia.


Adobe Reader XI 11.0.05 is a software program developed by Adobe Systems. During setup, the program creates a startup registration point in Windows in order to automatically start when any user boots the PC. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The primary executable is named wow_helper.exe. The setup package generally installs about 58 files and is usually about 114.16 MB (119,705,682 bytes). Relative to the overall usage of users who have this installed on their PCs, most are running Windows 7 (SP1) and Windows 8. While about 56% of users of Adobe Reader XI come from the United States, it is also popular in United Kingdom and Israel.
