Popup states: “Application blocked by security settings …” when running APT

Java now blocks APT from running by default. The workaround is to add “http://www.aptstudent.com” to the Exception Site List. The most recent updates to Java have removed the Medium Security Level, so that workaround no longer works.

Please follow the instructions below:

Add “http://www.aptstudent.com” (without the quotes) to the Exception Site List.



APT still isn’t working on my computer

First, make sure your computer has the right system requirements:

System Requirements


APT works on Windows, which should come with Java 7. If you do not have Java 7, download it here, and then install it.

APT must be run with the Sun/Oracle version of Java 7, do NOT use the OpenJDK (APT has problems saving course plans due to a bug in the OpenJDK).


APT works on 64-bit Intel-based Apple computers running Leopard (OS X 10.5). You must have the latest Java update installed (see Java for Mac OS X 10.5 Update 2).

For older Apple computers (includes 32-bit Intel based, Tiger and Leopard, and all Power PC based Apples), APT does not work as Apple has not released Java 7 for these configurations.

Second, clear your java cache (instructions on how to do so can be found here).

Third, make sure that you always start APT from the orange launch button on the homepage of this website.

If it’s still not working, send us a detailed email, and we’ll get back to you. Thanks!
