## Update the Windows Registry

Editing the registry entries in the new PME system is necessary if you want to:

- Specify a custom network diagram (instead of using the default network diagram) to be used in the Diagrams (Webreach) part of the Web Applications.
- Enable linking of custom device types (for example, those created with the MDI) to default diagrams in ION Vista.

Do NOT import any performance tuning settings from the old IONE SPMPME system. The default settings in PME 8.2 have been optimized for that system and should only be changed by experts with a deep understanding of the ramifications of the changes.

To customize the network diagram:

1. Start the Windows Registry Editor and browse to:
   - `HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Schneider Electric\Power Monitoring Expert\8.0\WebReach` [For 64-bit systems]. Path? 8.0 or 8.1?
   - `HKEY_LOCAL_MACHINE\SOFTWARE \Schneider Electric\Power Monitoring Expert\8.0\WebReach` [For 32-bit systems]. Path? 8.0 or 8.1?
2. Right-click to Add a new string value of NetworkDiagram.
3. Right-click NetworkDiagram, select Modify, and type the path and name of your custom network diagram in the Value data field.

   For example: `x-pml:/diagrams/ud/campus/campus_home.dgm`

4. Restart IIS on the system to apply the changes.

To enable the diagram linking in Vista, do the following:

1. Start the Windows Registry Editor and browse to:
   - `HKEY_LOCAL_MACHINE\SOFTWARE \Schneider Electric\Power Monitoring Expert\8.0\DeviceInfo` [For 64-bit systems]. Path? 8.0 or 8.1?
   - `HKEY_LOCAL_MACHINE\SOFTWARE \Schneider Electric\Power Monitoring Expert\8.0\DeviceInfo` [For 32-bit systems]. Path? 8.0 or 8.1?
2. Add the necessary entries for the custom device types.
