A recent AVG and Avast antivirus update is preventing DisplayFusion 9.9 from launching on some systems. If you're running into this issue, please update to the latest DisplayFusion 10.0 Beta.
Hello everyone!
We've recently had many reports of DisplayFusion 9.9 suddenly not launching. It appears that this is being caused by a recent AVG Antivirus update. The good news is that the latest DisplayFusion 10.0 Beta is not affected by this. If you download it and run the installer over top of your existing installation, that will fix it up.
If you've done this and it's still not working, please start a new topic, or submit a support request.
Thanks!
