MSiInstaller/Restart manager error

Occasionally, the Symphony Desktop Application (SDA) can restart unexpectedly without any error being displayed. You can check if an unexpected restart is due to a MSiInstaller/Restart Manager error by following the steps below:

1. From the SDA, select Show crash dump in Explorer from the Troubleshooting menu under Help (Figure 1):

2. Open Event Viewer and navigate to Application under Windows Logs (Figure 2):

3. Search for any errors relating to the MSiInstaller or Restart Manager (Figure 3):

4. If the error states Product: Symphony -- A more recent version of Symphony is already installed on this computer, this indicates your Windows configuration is pushing an installation of an older version of the SDA (Figure 4):

In this case, please notify your internal IT team and ask them to prevent the deployment of the older SDA.

If the error states something else, please contact the Symphony Support team at and inform them that you are experiencing issues with an unexpected restart of the SDA.
