Troubleshooting Runtime Errors in GFI MailEssentials

Information

To resolve runtime errors in GFI MailEssentials, follow these steps:

1. Check Available Disk Space:
   • Open File Explorer, right-click on the system drive (usually C:\), and select Properties to check available space.
   • Alternatively, open Command Prompt (cmd) as Administrator and run:

     wmic logicaldisk get size,freespace,caption

   • If disk space is low, delete unnecessary files, clear the %temp% folder, or expand disk space.
2. Verify Assembly Installation:
   • Ensure the DevExpress.Web.v11.2.dll is present in:

     C:\Program Files (x86)\GFI\MailEssentials\wwwconf\bin

   • If missing, reinstall the necessary DevExpress package.
3. Review Configuration File:
   • Check the web.config file, particularly line 92, for correct references to DevExpress.Web.v11.2 and ensure all dependencies are configured properly.
4. Clear .NET Temporary Files:
   • Stop IIS by running:

     iisreset /stop

   • Navigate to:

     C:\Windows\Microsoft.NET\Framework64\YourVersion\Temporary ASP.NET Files\MailEssentials

   • Delete the MailEssentials folder.
   • Restart IIS:

     iisreset /noforce

5. Restart GFI MailEssentials Services:
   • After resolving disk space issues and clearing temporary files, restart the MailEssentials services and test the application.
6. Update Software:
   • Ensure GFI MailEssentials is updated to the latest version to include fixes for known issues.

If the issue persists, provide specific error messages and logs for further analysis.
