NT/WinXP users can get around the installer by manually installing the game themselves. Note however that you must have at least NT 4.0 with Service Pack 3 in order to play the game. Also, Fallout should work fine but was not tested very much under NT.

1. First, create a folder for your game called fallout1/2 (ie c:\games\fallout1 or c:\games\fallout2).
   
2. Copy (CDROM):\program\win\falloutw.___ (Fallout 1) or (CDROM):\program\win\fallout2.___ (Fallout 2) to the folder you created and rename it to falloutw.exe/fallout2.exe.
   
3. Now you have four choices, depending on the installation size you want:
   • Small Installation: Do not copy anything else.
   
   
   • Medium Installation: Copy (CDROM):\master.dat (318MB) to your fallout folder (ie c:\games\fallout1 or c:\games\fallout2)
   
   
   • Big Installation: Copy Copy (CDROM):\master.dat (318MB) and (CDROM):\critter.dat (150MB) to your fallout folder (ie c:\games\fallout1 or c:\games\fallout2)
   
   
   • Humongous Installation: Copy Copy (CDROM):\master.dat (318MB), (CDROM):\critter.dat (150MB) and Copy the entire (CDROM):\data folder to your fallout folder (ie c:\games\fallout1 or c:\games\fallout2)
4. Create a text file in c:\games\fallout1 or c:\games\fallout2 called fallout.cfg or fallout2.cfg and add the following line to it, depending on your installation/game:

   Fallout 1:

     [system]

     free_space=0

   Fallout 2:

   • Small Installation:

     music_path2=(CDROM):\data\sound\music\
     
     [system]
     critter_dat=(CDROM):\critter.dat
     critter_patches=c:\games\fallout2\data
     master_dat=(CDROM):\master.dat
     master_patches=c:\games\fallout2\data
     
     
   • Medium Installation:
     [sound]
     music_path2=(CDROM):\data\sound\music\

     critter_patches=c:\games\fallout2\data

     critter_patches=c:\games\fallout2\data
     master_dat=c:\games\fallout2\master.dat
     master_patches=c:\games\fallout2\data
     
     
   • Humongous Installation:
     [sound]
     music_path1=c:\games\fallout2\data\sound\music\
     music_path2=(CDROM):\data\sound\music\
     
     [system]
     critter_dat=c:\games\fallout2\critter.dat
     critter_patches=c:\games\fallout2\data
     master_dat=c:\games\fallout2\master.dat
     master_patches=c:\games\fallout2\data
     
     NOTE German version:
     I just got word from fr33l that if you have the german version you also need to add:

     language=german

     under the [System] tab in the cfg file.

   
   
5. Next install the official patches for Fallout 1 or Fallout 2, it's easiest just to unzip/unrar them into the Fallout 1/2 folder.
   
6. Start the game by running the falloutw.exe or the fallout2.exe file.

1. Make a shortcut to the falloutw.exe or fallout2.exe file
   
2. Right click the shortcut, and select "Properties->Compatibility" and select either Win95,98
