Resolving Sage 50 Error 1935: Causes, Solutions, and Preventative Measures

[markjames5963]

When the Sage 50 Error 1935 appears, it indicates a vital system dependency is missing or not properly registered, disrupting access to Sage 50 accounting software. Specifically, the error message states:

“Error 1935. This program requires Microsoft Visual C++ 2005 SP1 Redistributable Package. Please install and try again.”

This points to issues with Microsoft Visual C++ 2005 Service Pack 1 not correctly validating during Sage 50’s initialization and license checks, which locks access to features.

Common triggers include:

• Missing or corrupted Visual C++ redistributables
• Incomplete Sage 50 installation
• .NET framework conflicts
• Limited user permissions

To resolve, systematically:

1. Reinstall latest compatible Visual C++ 2005 SP1 packages
2. Repair .NET Framework installs through Control Panel
3. Completely uninstall and reinstall Sage 50
4. Ensure Sage 50 runs as administrator

Preventively:

• Maintain Sage 50 workstations stably
• Allow uninterrupted updates
• Validate dependencies periodically
• Keep permissions and exclusions updated
• Promptly patch Visual C++ updates

Having appropriate frameworks, libraries and runtimes properly registered maintains compliance for access validation. For tricky cases, Sage support can provide advanced environment-specific troubleshooting.
