Hi @Pramod_Mangale ,

Could you maybe try adding the namespace in the imports section and check :

System.Management

Yes I added that namespaces and tried but still same issue

Hi @Pramod_Mangale

It looks like the System.Management.ManagementObject namespace is not available in the remote machine. You need to ensure that the .NET Framework version on the remote machine includes the specified namespace.

Can you try running the following command in the cmd & let us know the .Net version:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP" /s

Best Regards.

Giving error like system was unable to find specified registry key or value

@Pramod_Mangale

Assuming that you run the cmd with admin privileges, can you please check & confirm if .NET Framework is installed on the remote server or not.

Just to make sure, please try running the following script in the PowerShell:

Get-ChildItem ‘HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP’ -Recurse | Get-ItemProperty -Name Version -EA 0 | Where { $_.PSChildName -Match ‘^(?!S)\p{L}’} | Select PSChildName, Version

Best Regards.

It is showing as v 4.0

@Pramod_Mangale

The recommended .NET version for UiPath is 4.6.1 or later. As long as you have the necessary dependencies installed and configured properly. UiPath also supports earlier versions of .NET, including 4.0.

You can try doing one of these things:

  1. It’s better to upgrade the .Net Version.
  2. Make sure all thé configurations are in place & System.Management.ManagementObject namespace is included.

Hope this helps,
Best Regards.
