Product Line

Satchwell BAS & Sigma

Environment

Sigma Remote Client

Cause

The error occurs because the incorrect version of Sigma Client software has been installed on the remote client PC.

For example:

• The site is running Sigma 4.05 SEB
• The remote client was mistakenly installed with Sigma 4.06

Sigma software versions must match across all components (Client/Server and Remote Clients). Mixing versions will result in runtime errors and instability.

Resolution

To resolve the issue:

1. Verify the site’s Sigma software version:

   • Open Sigma System Manager
   • Navigate to Help > About Sigma
   • Note the build number displayed

2. Ensure the Remote Client matches the site version:

   • Uninstall the incorrect version (e.g., Sigma 4.06)
   • Install the correct version (e.g., Sigma 4.05 SEB) that matches the site

⚠️ Important: Always confirm the site’s Sigma version before installing or updating any Remote Clients.
