If you are using a PC and want to provide your 4D Business Kit server with more available memory, you can do so easily with 4D Customizer Plus. For version 1.2 and above, you will need to use 4D Customizer Plus for 4D v6.8 (otherwise you can use version 6.7). You can go to https://www.4d.com/downloads/products.html and download the current release of 4D Customizer Plus. After you have launched the self-extracting application, just drag-and-drop the 4D Business Kit application icon on top of the 4D Customizer Plus icon. The Customizer Plus application will open your Business Kit application property settings and allow you to customize them.
Select Preferences and then increase the number of blocks of main memory to be allocated to your 4D Business Kit application.
