For anyone venturing into trying this feature out, it might actually block *.BIN extensions, at least in Openoffice (soffice.Bin), for some strange reason, even though this extension is not listed as one of the two (.EXE & .COM) it manages. I've discovered the best way to troubleshoot issues using AppLocker is to change the AppLocker-> Configure rule enforcement-> Executable files from "Enforce rules" to "Audit only"; this will enable all applications to run, and anything that would have been blocked will be logged. Then, open up the application that was being blocked previously by AppLocker. Then, go to Start, type in event vie... then choose Event Viewer at the top of Start menu -> Applications and services logs-> Microsoft-> Windows-> AppLocker-> EXE and DLL; you should see in the log entries the program that would have been blocked had AppLocker rules been enforced. Using the information, you can easily modify the rule necessary so the application will not be blocked.
