Enter the following in Promt.
? Perform environment setup (recommended)? Yes
? Set PM2_HOME? Yes
? PM2_HOME value (this path should be accessible to the service user and should not contain any “user-context” variables [e.g. %APPDATA%]): c:\etc\.pm2\
? Set PM2_SERVICE_SCRIPTS (the list of start-up scripts for pm2)? No
? Set PM2_SERVICE_PM2_DIR (the location of the global pm2 to use with the service)
? [recommended] Yes ? Specify the directory containing the pm2 version to be used by the service C:\USERS\<USER>\APPDATA\ROAMING\NPM\node_modules\pm2\index.js
Start the servive by access to Service
