My experience shows that the Software Updater tool is not working perfectly. For example: I am using Foxit Reader to view PDF document files. The version being used is 7.3.4. I use Software Updater tool to check whether the later version of Foxit Reader is released but the tool is not capable of detecting the latest version of Foxit Reader. In other words, Foxit Reader is not always listed in outdated softwares list meanwhile its latest version now is 220.127.116.114.
