Summary

In the Workflow Configuration Manager, when selecting a database type, you may receive the following message:

Unable to find the requested .Net Framework Data Provider. It may not be installed.

The log file in C:\ProgramData\Laserfiche\WF\ConfigurationLogs will contain an entry similar to the following:

The 'DbProviderFactories' section can only appear once per config file.

Cause

In certain situations, the .NET Framework installation may create a duplicate DbProviderFactories element in the machine.config file.

Resolution

Modify the .NET Framework machine.config file to remove the extraneous <DbProviderFactories /> element.

Browse to C:\Windows\Microsoft.NET and for each architecture and version subfolder, open up the machine.config file and make sure there is only a single <DbProviderFactories> section.
