Error - Vyopta CPM Data Collector is already running. Exiting...

When installing the Next Generation Data Collector, you may encounter an error that indicates another instance of the Data Collector is already running on the server. To resolve this issue, you must first find the services running on the server that are using the Non Sucking Service Manager (NSSM). To do this, run the following command in Powershell as an Administrator on the server:

Get-WmiObject win32_service | ?{$_.PathName -like '*nssm*'} | select Name, DisplayName, State, PathName

You should only see one service as shown in the screenshot below:

If you see other services here, you will need to shut down the other service to install the Data Collector on the server. If you are not able to shut down the other service, you may have to install the Data Collector on another server that doesn't have applications that are dependent on NSSM. This is a known issue, and we will address this issue of coexistent with other NSSM apps in an upcoming release.

SC DELETE VyoptaCPMDataCollectorService

Once you have successfully deleted the old service, you should be able to run the following command inside of your Vyopta Collector folder to recreate the service. Make sure you are using an Administrator: Command Prompt window to run the command below:

vyoptacollector.exe -install

After this point, the new service should be available for you to restart. To uninstall the Vyopta CPM Data Collector service, refer to the How to Uninstall the Next Generation EPM  article.
