Environment

• Datto RMM

Cause

• The installation of the Microsoft .NET Framework on the endpoint is corrupt.
• Residual files in %Program files(x86)%\CentraStage and %Programdata%\CentraStage\ folders prevent installation. 

Resolution

On the endpoint machine, run the .NET Repair tool from Windows or an SFC /scannow operation from an elevated Command Prompt session to resolve the issue.

If the issue persists, perform a clean uninstall, then reinstall the agent. Contact Datto RMM Support if you need further assistance.
