Who is this article for?

  Users who encounter the error when signing in to the desktop client.

When launching the application you may see the error:

  file [...]\VISION.FDB is not a valid database

This happens because that local file has become corrupt.  This article explains how to resolve the issue.

1. Issue

When launching the application, an error dialog appears:

This happens because the file vision.fdb at %localappdata%\Vision\[instance name]\LocalData\ has become corrupt in some way.

This file contains a local copy of some configuration data (e.g. dropdown lists).  We can resolve the issue by replacing the file and no user data will be affected.

2. Solution

• Open File Explorer and go to the path shown in the error message.  In the example shown in the image above this would be C:\USERS\KARL\APPDATA\LOCAL\VISION\PENTANA - PRD\LOCALDATA, your equivalent will be %localappdata%\Vision\[instance name]\LocalData.
• Delete the file vision.fdb.
• Launch the application again.  If this fails with an error "The application is already running" then follow the instructions shown here:  Understanding the launch error "The application is already running".

This solution works because there is a backup copy of the faulty file (called vision.bak), and if vision.fdb is missing then the application simply creates a new copy, based on the backup.
