To install in Photoshop, in the Actions panel, go to Load Actions. Point it to where you have the "VerticalCross to UDKTextureCube.atn" file located. Open a standard vertical cross image in Photoshop and run the action on it. Note that the vertical cross image you use needs to be in an 8-bit per channel, low dynamic range format. The action does not support toning HDR files. So either download a pre-toned cross, or tone the cross and convert it to 24-bit before you run the script.
