Add "Run in Separate Memory Space" to Windows 7 Run Command
Information
All DOS and 16-bit programs run on Windows 7 in the Windows Virtual DOS Machine (VDM) program. VDM simulates a 16-bit environment, complete with the DLLs required by 16-bit programs.
By default 16-bit programs run in a single VDM with a shared memory space. They share the memory space allocated to the vdm process and therefore, they cannot run simultaneously.
This will show you how to add the Run in Separate Memory Space check box to the Windows 7 Run command dialog box. When Run in Separate Memory Space is checked, a 16-bit program runs in a dedicated (not shared) (VDM) process with a separate memory space.
