Okay so I just checked it out - when you download the zip file and first open up there are three options: a win32 folder, a win64 folder, and an application called WindowsIconUpdater. The WindowsIconUpdater literally just updates the game file icons - not really sure why it's there!
To access the game itself, just click on either the win32 (for 32-bit processors) or win64 folder (for 64-bit processors) and then within the folder there should be an executable file or application called TRAINBOW. You will probably be prompted to extract all of the files from the zip, which you should do! Then go into the unzipped folder again, click on the TRAINBOW application, and the game should load up no problem!
Thanks for your patience and please enjoy! Let me know what you think.
