Phaewalker There's nothing obvious in your dxdiag, and I'm not sure how the App is failing to install to the point that it can be used or Revo can detect it. But what you can do from here is manually delete the main files and use Piriform's CCleaner (the free version) to try to clean out everything else.
Make sure no EA-related services are running in the Task Manager, including in the background processes list. Open C:\Program Files\Electronic Arts and delete the EA Desktop folder. Use CCleaner to search for anything EA App-related, review the list to make sure nothing you want to keep was flagged, and delete the rest. Then restart your computer (first) and try again to install the App, again with your antivirus disabled.
