Config Wizard : Farm products and patches were not detected but already installed

Question

I am facing an annoying issue with my SharePoint 2010 platform, here is the situation :

1. SharePoint 2010 Standard with Office Web Apps
2. Multi-language
3. 2 WFE

When running the configuration wizard, one of my server is in error mode :

"Farm products and patches". The following update is missing for one server :"Microsoft Office Web Apps Front End Components".

But it is already installed. Even if I start again the setup, I have a pop up saying that this update is already installed.

I have run several PowerShell commands like Get-SPProduct -local or running the wizard with PowerShell without success.

Any ideas?

For your information, it was related to a language pack that was uninstalled, and we had to delete the associated reference in the Registry
