Project Remaster is a BF2142 modification which adds new HD environment textures, weapon animations, full offline support and many other elements.
Just copy and overwrite the Battlefield 2142 folder with the old one ! Example for folder direction : C:\Program Files (x86)\Electronic Arts\ For those, who still have problems with the starting and login, here is a solution !. You will have 3 different ".exe" files, the first one is the "BF2142_Offline.exe" which allows you to start the game without the master server connection and the other two ".exe" files are located under the Mod folder, they allow to start the mod directly. *Note ; the window mode.exe comes with a resolution of 1024x800 . I apologize for the huge effort and problems so far !
