Go to this directory in your DCS install location...

C:\DCS Open Beta\DCS World OpenBeta\Bazar\World\textures\     (or whatever drive you installed on)

Drag all of the .dds files from this folder directly onto the AeroWeapons.zip file. 7zip will copy the new files to the existing zip file. Overwrite any existing files if 7zip asks you to.

Note: I use 7zip because it is much better.
