I installed and tried FileHippo Update Checker, and the software located 7 software products on my computer that were in need of upgrades. In addition FileHippo Update Checker found 3 other upgrades that were for beta software. FileHippo Update Checker is simple to use and it is free. Here is what they say on their web site:
What is it?
The Update Checker will scan your computer for installed software, check the versions and then send this information to FileHippo.com to see if there are any newer releases. These are then neatly displayed in your browser for you to download. Please note that not all programs are supported.
However, even though the program is limited, I still believe it is worth trying. The biggest benefit is that it does a good job plus it is free.
