  2. Next type "Command Prompt" into the search bar.
  3. Once the "Command Prompt" has been found right click it and choose "Run as administrator".
  4. Enter the following command into the command prompt and press the enter key: bcdedit /set IncreaseUserVA 3072

If you wish to change this setting back to the default settings; simply run through steps 1-3 again however instead of the command listed in "Step 2" type the following and press enter:

bcdedit /deletevalue IncreaseUserVa

Once these steps are completed Tobii Pro Studio 3.2.3 and later, will be able to use 3GB instead of 2GB of RAM on your Windows 7 or Windows 8.1 32-Bit Operating System.
