Performance recommendations for Sage HRMS client when using Aatrix

Summary

Third-party antivirus software quarantines Sage HRMS and Aatrix files leading to performance issues and errors such as: "There was an error initializing Sage HRMS: The system can’t find the file specified."

Resolution

To ensure Sage HRMS functions properly, exclude its files and folders from third-party antivirus scans. Lowering User Account Control (UAC) to "Never Notify" may also help.

Users need adequate permissions to access and modify key files; otherwise, issues with saving drafts, histories, and updates may occur.

The Aatrix user should have local admin rights, and all relevant Sage directories must be visible (not hidden).

In your third-party antivirus program, add the following exclusions or white list:  

  • C:\Windows\Microsoft.NET
  • On a 64-bit machine – C:\%ServerName%\SageHRMSServer
  • On a 64-bit machine - C:\Program Files (x86)\Aatrix Software
  • On a 32-bit machine - C:\Program Files\Aatrix Software
  • HR Client - C:\Program Files (x86)\Sage\Sage HRMS Client
  • PR Client - C:\Program Files (x86)\Sage\Sage Accpac
  • For Windows 10/11
    • C:\Users\%UserName%\AppData\Roaming\Aatrix Software and C:\Users\%UserName%\AppData
    • C:\ProgramData\Aatrix Software
    • C:\Users\%UserName%\AppData\Local\Aatrix Software
    • C:\Users\%UserName%\AppData\Local\Temp\Aatrix Software
