When Windows gives you notification, you should be able to click it to open where it stores info from deletion. Then you can just set the files to be non-dangerous and will put them where they should be in. If using Manual, you need to drop the folder inside root/mods and if you have Game_Mod installed properly with newest version, it should appear under Mods tab

I am having problems. When asking to install th game it asks me to select the folder with an exe to install the mod, and when selecting CoDWaW.exe it crashes with no chance to install. Please help because the map looks sick
