Fix your update checker
It says I need to install Defraggler version 2.15.742. I do so and rescan and it still says I need Defraggler 2.15.742. I run Defraggler and check its version. It is indeed 2,15.742. I restarted my computer and ran your update checker agan and it still claims I need version 2.15.742, The update checker from filehippo.com doesn't make this mistake!
I am going to remove this from my computer. It claims updates needed when that is not the case.
