Hi @HS79, Thanks for reaching out. Based on the information provided and screenshot of error message, it appears that there is a problem with the client installation of Sage HRMS.  Uninstall Sage HRMS client off the workstation and install client again as the administrator. 

Hi,

  Thank you very much for the information you have provided. I have initially installed the software as an administrator, but after removing and reinstalling the software the error message is gone.
