Lightbox ajax jquery doesn't run

Q: Dear Support,

I've bought the app. and installed it. But when i click it won't run. What am i doing wrong?
I use Windows 7.
Could you help me?

Thank you.

A: Try to do the following:

Control panel -> System -> Advanced system settings -> (Performance) Settings -> Data Execution Prevention.

Turn off DEP or add the app. in the exception list.

If the problem persists, then try to add the app. in the whitelist of your antivirus.
