CATIA Magic 2026x upgrade from UAF to UAF 1.3

Hello,

 

I've installed CATIA Magic 2026x, but I'm steel in UAF and not in UAF 1.3.

When I try to select the UAF 1.3 I have a message

 

I didn't find the way to do this upgrade through the wikipages or to download the plugin.

 

Could you help me ? Do you have a step by step to do this upgrade ?

 

Thank per advance,

Frédéric
