Out of memory crashes on 32-bit Windows systems:
For playing Dreamfall Chapters, our minimum requirements state that your computer should have more than 3 GB of RAM, but we also highly recommend that your computer has more RAM than this available. Also, a 64-bit operating system is actually required for any program to be able to access more than ~3 GB of RAM

Therefore, if you have a 32-bit operating system, you may experience occasional out-of-memory crashes whilst playing the game. Please be advised that for all issues regarding out-of-memory crashes we advise you to:

Close any additional programs running in the background that is not needed while playing the game, to free up memory.

Turn down in-game graphics settings, especially the Visual/Graphics Quality setting, to reduce memory usage. We also recommend restarting the game after changing the Visual/Graphics Quality setting.

Additionally, there is a known method for allowing applications to use additional RAM in 32-bit operating systems which may help reduce/eliminate out-of-memory crashes.
To enable this, please click the link below and follow the instructions under the "Instructions for allowing applications to use more RAM in 32-bit operating systems"-spoiler in the first post:

Please note that the instructions in the Windows 7 section also applies to Windows 8 users.
To find/open the Command Prompt on Windows 8, you can open the start-menu, write "cmd.exe" and follow the rest of the instructions listed.
