I can't update. maybe cause different partition?

you might want to look at (or perhaps find similar):

• https://community.adobe.com/t5/lightroom-classic-discussions/update-failed-updates-have-been-supressed-by-the-administrator-how-may-i-solve-this/td-p/8664406

I may have the wrong impressions as to your language, Italian?

A similar error message might be:

"gli aggiornamenti sono disattivati ​​su questo computer: contatta l'amministratore"

that from:

"updates are deactivated on this computer: contact the admin"

Point being the above is what I used on an Internet search.

What is the error message?
