Thanks Draco for the information and Thanks to Meridian for the instructional video. I seemed to have been able to install OpenXcom properly. Now the Redux Mod is causing me problems. The mod says it requires this nightly 2015_10_01_0503 or later. This nightly is no longer there. So I downloaded 2015_10_10_0133 instead since the latest Redux version is Oct. 14, 2015. I followed step by step what Meridian did on his videos with the versions I have. The game opens with the nightly version on the title screen. And I play/tested a little bit of the game and all seems fine. What I go to options and then mods, I see where I can potentially change the mod from UFO to an installed mod. So I believe I have this part figured out.
I've tried to install the Redux files a few different ways, but I can't seem to get the Redux version in the Options/mods selector.
So now I have a folder on my desktop called "openxcom". Inside I have the folders "common, standard, TFTD(empty, i didin't buy this game yet), UFO(with the files from GEODATA to UNITS in steam folder as per Meridian videos instructions). And 4 files "changelog.txt, license.txt, openxcom.exe, and readme.md".
I now have the redux download extracted on my desktop in a folder called "redux". This is where I seem to be stuck. I tried to integrate this files several different ways. Nothing seems to work. Please note that after every attempt, I make sure that the files are back to where they were before trying to install redux.
Sorry to be a bother with this, as it should be simple enough, but I can't seem to get it to work.
Thanks in advance for your help.
Marc.
