According to this AppD Docs page https://docs.appdynamics.com/display/PRO45/Install+the+Database+Agent+as+a+Windows+Service
I should be able to run InstallService.vbs to install the DB agent as a windows service.
However, when I download the dbagent-18.104.22.1685.zip I don't see an InstallService.vbs script contained in the package. What am I missing here?
You have to download the Windows specific zip from https://download.appdynamics.com/download/#version=&apm=db%2Cappd4db&os=&platform_admin_os=&appdynam... and it will contain the required files.
