Troubleshooting Quick Reference (Cheat Sheet)

Fix 4: Enable TLS 1.2 for Database Connections

Because v244120 mandates modern TLS, older systems may fail.

Registry fix (run as admin):

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SchUseStrongCrypto"=dword:00000001

Then reboot. This forces .NET applications to use TLS 1.2.

How to test it out:

1. Open the SQL Code Completion options within the Excel Add-in settings.
2. Enable the AI Assistant and connect it to your preferred provider (OpenAI API key or Azure endpoint).
3. Make a change to a database object (like editing a View).
4. Go to the Commit Changes window.
5. Look for the AI sparkle icon in the "Comment" text box. Click it, and watch it generate a commit message based on your code changes.

This feature stands out because it bridges the gap between "writing code" and "managing code," saving tedious minutes on administrative tasks so you can focus on the data analysis in Excel. devart excel addins v244120 fix best

Preventing Future Issues with Devart Excel Addins

Once you have applied the best fix, follow these preventive measures:

• Automatic Updates: Disable auto-update for Devart if you need stability (update manually after testing on a VM).
• Backup Settings: Export your connection profiles and query definitions regularly.
• Excel Version Compatibility: Devart v244120 works best with Excel 2016, 2019, 2021, and 365 (Build 16.0.14026.21000 or newer).
• Use 64-bit Excel: Devart add-ins are more stable in 64-bit Excel. Avoid 32-bit if your dataset exceeds 2GB.

Minor Drawbacks

• No UI overhaul – The ribbon and query editor look identical to v24.2.x. If you wanted modern dark mode support, this isn’t it.
• One regression (acknowledged by Devart support forums): Custom OData feeds with complex filters may require re-entering the filter expression once after upgrade.
