When I start AVG Tune Up 2014, it says the integrator.exe can't function. What can I do?
This seems to be an internal error of the application. To fix it, you can try to uninstall the software and then install it again. You should also upgrade your version to the latest one available before you install the program again on your computer. By doing this, some errors like this one might be fixed. You can also visit the official forum where this kind of subjects are being discussed.
