The SDK includes two batch files you can use to switch between the retail and debugging versions of MMSYSTEM:
| Batch File | Description |
| MMN2D.BAT | Installs the debugging version. |
| MMD2N.BAT | Installs the retail version. |
Note:
The MMN2D.BAT and MMD2N.BAT batch files install the debugging and retail versions of Windows, as well as MMSYSTEM.
