ClassFactory cannot supply requested class

I have an issue with an iFix v5.8 installation on my computer.
I want to install iFix v5.8, with v5.8 SP1 on my computer.

I restored an existing v5.8 HMI application to my computer, but each time I switch from configure mode to run mode, I receive the error message 'ClassFactory cannot supply requested class'.
The VBA points to my custom alstom.fxg module.

This application is running correctly on the production computer, but I can't make it run to my machine.

I can compile the alstom.fxg module in VBA without errors.
The customer alstom.fxg module is not showing any missing references.

I tried to deinstall and reinstall iFix.
I tried to perform a repair of iFix.

Nothing seams to fix the issue.

Any idea on how to fix this?

Thanks,
