I am working on:

Microsoft Windows [Version 10.0.19045.4529]

I’m trying to install a service I’m working on:

C:LocalDevVisualStudioMultiStatsCSservicebinRelease>C:WindowsMicrosoft.NETFramework64v4.0.30319InstallUtil C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.exe
Microsoft (R) .NET Framework Installation utility Version 4.8.9037.0
Copyright (C) Microsoft Corporation.  All rights reserved.


Running a transacted installation.

Beginning the Install phase of the installation.
See the contents of the log file for the C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.exe assembly's progress.
The file is located at C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.InstallLog.
Installing assembly 'C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.exe'.
Affected parameters are:
   logtoconsole =
   assemblypath = C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.exe
   logfile = C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.InstallLog

An exception occurred during the Install phase.

The Rollback phase of the installation is beginning.

Rolling back assembly 'C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.exe'.
Affected parameters are:
   logtoconsole =
   assemblypath = C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.exe
   logfile = C:LocalDevVisualStudioMultiStatsCSservicebinReleaseMultiStatsCSservice.InstallLog
An exception occurred during the Rollback phase of the System.ServiceProcess.ServiceProcessInstaller installer.
System.NullReferenceException: Object reference not set to an instance of an object.
An exception occurred during the Rollback phase of the installation. This exception will be ignored and the rollback will continue. However, the machine might not fully revert to its initial state after the rollback is complete.

The Rollback phase completed successfully.

The transacted install has completed.
The installation failed, and the rollback has been performed.

I’ve checked my account and I am shown as having Administrator privileges, what else could explain the reason why the service will not install?
