Incompatible runner: unmet requirements

• Exists=>(DotNetFramework(4\.[5-9]{1}.*|[5-9]{1}.*|\d{2,}.*)_x86|Mono(3\.[2-9]{1}.*|3\.\d{2,}.*|[4-9]{1}.*|[\d]{2,}.*)) exists

• .NET Framework 4.7 is installed, confirmed by the registry key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\V4\Full
• Powershell is installed, confirmed by the registry key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine (and  Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\3\PowerShellEngine)
• I have additionally installed MSBuild and NUnit on the server
• I have also added the following to c:\TeamCity\buildAgent\conf\buildAgent.properties:

Please let me know exactly what other information/log files you require.

Thanks
