Symptoms

When you start Zoo Tycoon 2, you receive an error message: 

You need at least 256 MB of system memory to run Zoo Tycoon 2. (___ MB detected).

Cause

This error may occur if you try to run the game on a 64-bit operating system with more than 4GB of RAM (Random Access Memory). 

Resolution

Zoo Tycoon 2 is compatible with a 32-bit or 64-bit operating system with less than 4GB of RAM. 

To resolve this issue, upgrade your version of the game by purchasing and installing expansion packs such as Zoo Tycoon 2: African Adventure or Zoo Tycoon 2: Extinct Animals.

Note To play either of the expansion packs, you must have Zoo Tycoon 2 installed. 


You may also decide to return Zoo Tycoon 2 to the point of purchase and obtain Zoo Tycoon 2: Ultimate Collection instead. Zoo Tycoon 2: Ultimate Collection includes the original game and the Extinct Animals, Marine Mania, Endangered Species and African Adventure expansion packs.
