When starting a 16bit application you have the option of running it in a seperate virtual machine. From this setting you can change the default setting for using VDM's.
Having a seperate virtual machine, has the advantage that if the applications crashes only that one application is affected, on the down side though it takes up a bit more system resources. It's up to you decide which is more important.

  1. Open the registry and find the key and value below, if they don't already exist create them.

  2. 2. Change the value of 'DefaultSeparateVDM' to either 'Yes' or 'No'.

Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOW]
Value Name: DefaultSeparateVDM
Data Type: REG_SZ
Data: 'Yes' or 'No'
