Problems Installing Agent Service on Windows 10 für Aras 12 SP 07


I tried to install Agent Server and Conversion Server on WIN 10.

The entire installation works fine except of the installation of Agent Server.

So i first installed all the other Features and then tried to install Agent Server after, by using "modifying the installation" in the installer and to include Aras Agent Server then.

The Installation works fine up until to the point when the service should be started. It simply fails to do so every time.

The Windows Event Log shows the Following Error Message:

Source: Aras Innovator Agent Event ID : 0 Task Category: None Level: Error ..


Service cannot be started. System.NullReferenceException: Object reference not set to an instance of an object.
at Aras.Server.Agent.Service.HostingService.OnStop() in C:\Builds\CI\21092\Innovator.git\CompilableCode\Aras.Server.Agent\Aras.Server.Agent.Service\HostingService.cs:line 74

Can it be the prerequisites .NET Core 2.8 and Framwork 4.7? I thought i did install both correctly tho.

Does anyone have a suggestion about that?
Many Thanks in advance!
