Memory Error

Windows 32-bit and 64-bit operating systems have a default RAM memory limit of 1.5GB per 32-bit application instance.  In short, if you are running either version of Windows there is, by default, a 1.5GB RAM limit per instance of the 32-bit version of VDM, regardless of how much RAM is available on your workstation.

For Windows Vista and Windows 7 32-bit and 64-bit workstations you can increase the maximum allowed RAM per 32-bit application instance by running the following command at the command prompt.  Please note that you must have the physical RAM available on your workstation to support this command.

bcdedit.exe /set IncreaseUserVa 3072

Once the command has been executed, please restart your workstation.

As of v4.4.1.0 VDM is available in both 32-bit and 64-bit versions and both are located in the BridgeWorks VDM installation folder.  VDM.exe is the 32-bit version and VDM64.exe is the 64-bit version*.

*Please note that in order to run VDM64 for ODBC or OLEDB connections you must have a support 64-bit version of the ODBC or OLEDB driver installed and configured.
