How to set up the 3 GB option like in Windows XP for 32 bit VISTA or Windows 7, to extend the virtual address space from 2 GB to 3 GB for a 32 bit process?
If one of the following error messages show up, setting up the 3 GB option might be very helpful or even necessary: - 'A memory allocation failed. The virtual address space of the process has been used completely or does not include a coherent free block of sufficient size'. - 'Insufficient memory.'/'Out of memory'. - 'Error: Cannot load background file'. - 'Error in memory management. No free heap handle'. - 'Building connection legs...'.
To extend the address allocation space used by a 32 bit process, you can use the command BCDEDIT: 1) Look in the start menu for a shortcut to the command prompt. 2) Right click it and open it 'as administrator'. 3) Use this option: BCDEDIT /Set IncreaseUserVa 2700 Alternatively use this option: BCDEDIT /SET LOADOPTIONS ' /3GB /DISABLE_INTEGRITY_CHECKS' 4) Reboot the computer.
Please note: The use of these options on any 64 bit system is not recommended. PTV AG is not liable for any dammage caused by using these options.
