Benvenuto nell'odissea infinita di quell'errore se vuoi ti posto la risposta che mi ha dato l'assistenza per lo stesso errore che avevo io. L'unico modo che io avevo era reinstallare il gioco ogni aggiornamento o hotfix

Hi Smilzo,

Thank you for contacting Microsoft Flight Simulator Support today. You do not need to re-enter the code. The Premium edition content is tied to the MS Store account in which it was redeemed.

The first time you set up the game you chose the installation path. This is the folder that the launcher is scanning to retrieve the content. If the launcher finds that this folder is empty or missing (does not exist anymore), it will try re-downloading the missing packages. If you install additional packages outside of this folder, the launcher will not be able to retrieve the corresponding content.

To fix this issue, please update the UserCfg.opt file to point the launcher to the correct folder. To do so, follow the instructions from our knowledge base article: Why am I redownloading all the packages after each update?

Kind regards,
Microsoft Flight Simulator Support Team

Giusto per essere corretto, a me non ha risolto il problema, ma tu potresti essere piu fortunato. Io ho fatto una cosa drastica, HD nuovo, nuovo SO, nuova installazione FS2020 e dual boot in avvio del pc cosi decido se aprire il disco con solo fs2020 istallato, per ora va, ma attendo con ansia il prossimo aggiornamento per capire se ho risolto o no.

@smilzo Sono stato più fortunato, dopo aver cliccato per ben 22 volte su gioca il sim è partito, sembra funzionare. Grazie comunque per l'aiuto terrò conto di quanto hai scritto.

Spero,che rimanendo scritto nel forum, possa aiutare anche altri che incappano in questo odioso problema.

Io sono incappato in questo odioso problema, ti faccio un riassunto dei suggerimenti che generosamente mi hanno dato e che mi hanno risolto questa seccatura inutile.

Come ho sempre detto, non sono bravo al computer e quindi ho avuto bisogno del mio assemblatore che, seguendo i consigli avuti nel forum, ha sbloccato la situazione.

In breve:

1) Liberazione di spazio inutile

2) Aggiornamento drivers vari

3) Aggiornamenti vari

4) Via le mod dalla Community

5) Miracolo: si è aperto MSFS 2020 con aggiornamento 1.18.15.0

6) GESTORE CONTENUTI: aggiornamento di tutte le mod in esso contenute

7) GESTORE CONTENUTI: eliminazione A320 Fly By Ware 

8) GESTORE CONTENUTI: eliminazione delle mod (doppioni) con Xbox

9) rientro al desktop principale

10) Riavvio 

11) Apertura di MSFS 2020

12) Incrocio di dita e orazioni a tutto andare anche in latino...

13) Miracolo!!!!!

14) E' andata!!!

P.S. non ricordo se ho eliminato prima A320 FBW e fatto gli aggiornamenti o viceversa. Ricordo però che per ultimi ho eliminato i doppioni con Xbox.
