How to update Clover

Hello,

I installed my hackintosh 2 year ago. It is running well on Mojave, but, as I am considering to replace my graphic card with a more recent one (I have a Radeon RX Vega 64 8 Go), I understood that I should first update Clover

As of today, I am running with Clover 4920.

I have downloaded latest version of Clover Configurator. (5.18.3.0) and when going to "Install/Update" Clover it says that there is a newer version available (5136)

Clicking on "Update", it downloads and executes installer, no error message.

Then I reboot, but I can see that Clover remains in 4920. The update is not effective.

I would be more than grateful if anyone can help :-)
