[andrew-stclair]

Bug Report

System Information

• Operating System (Including distribution name and version number)
  Microsoft Windows Server 2016 Standard
  10.0.14393 Build 14393
• AMP version and build date (Always use the version number, 'latest' is not valid!)
  2.0.6.2
  unsure what build date, it was downloaded fresh today, 7th Sep, 2020
• Which AMP release stream you're using (Mainline, Nightly or FastTrack)
  Mainline

I confirm:

• that I have searched for an existing bug report for this issue.
• that I am using the latest available version of AMP.
• that my operating system is up-to-date.

Symptoms

AMP Instance Manager GUI does nothing when i try to open it, does not open a window or anything

AMP Instance Manager CLI errors out no matter what i do

C:\Program Files\CubeCoders Limited\AMP>ampinstmgr upgradeall

Unhandled Exception: System.MissingMethodException: Method not found: 'Void InstanceManagerPlugin.LocalInstanceManager..ctor(ModuleShared.ILogger, ModuleShared.IAuditLog, ModuleShared.IPlatformInfo, ModuleShared.IRunningTasksManager, ModuleShared.IFeatureManager, GSMyAdmin.Authentication.IAuthenticationProvider, ModuleShared.IAMPInstanceInfo)'.
   at InstanceManagerCLI.Core.Run()
   at InstanceManagerCLI.Program.Main()

Reproduction

• Install version 2.0.4.0
• Setup instances as required, ones used in my case are McMyAdmin, 7Days2Die, Factorio and Counter-Strike: Global Offensive
  (Should be noted, the McMyAdmin instance is using a license for McMyAdmin2, the rest are using a single license for AMP purchased a month or so ago)
• Use the installer for AMP version 2.0.6.2 downloaded from the cube coders website following the upgrading instructions from the Wiki
• At this point, both the gui and cli fail to function

Can you tell us what user you are using for AMP? Are you running it as an Administrator?

You need to run the setup in repair mode, then reboot the machine.
