Why image gallery html doesn't start?

Q: Dear support,

I really want to use the free version but CAN NOT INSTALL the free version. After I've downloaded the version it gives me an error, VISUALLIGHTBOX HAS stopped working.

Could you assist me with the download and installation, please?i

A: Try to do the following:

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

Turn off DEP or add VisualLightBox in the exception list.
