Ok, I will give you a run down on what I have done so far. Running windows 7 pro 64 bit version. Essentially first couple of time I tried to install it I may have missed a step or two. After reading a lot of instructions I went for my next attempt First - I uninstalled the Mod, IE: I went to control panel found the mod right clicked and uninstalled. If there was anything else I should have done I didnt know. Second - I verfied the files on steam. Third - I opened each verions of xcom twice. Letting it sit for a bit each time I went to the menu AND after I exited to the desktop. Forth - I went into offline mode and then exited steam. Fifth - I installed the mod, Long War 3 EW Beta 9a-88-3-0b9a Sixth - I start steam in offline mode and open EW (note: if I open EU it runs fine but with no mod changes. Which I assume should be normal since Im trying for the EW mod anyway) Seventh - It crashes, Says: Xcom EW has stopped working windows is searching for a solution. When it stops it give me a genaric paragraph about finding solutions etc. Eighth - I wait for about 1 minute and I repeat try to open it again. 1 of 2 things happens. 1. A repeat of step seven. 2. Steam says completeing installation 0%. It never advances in that installation and says the servers cannot be found. Which is expected since its in offline mode. If #2 happens I will make a 3rd attempt to open EW After reading some of the links you gave me. Most of which Im not fully understanding, but one thing had caught my attenion and that was installing steam in another folder away from Program files which I did not do before hand. Had no clue to do so. Thus I followed its instructions on doing so. Then repeated the above steps exactly and got the same results. Added note when I verify files after each uninstal I am able to play the vanilla just fine.
