Error starting D12 after Settings Migration

[M.Joos 29]

After I installed D12 I tried to migrate the D11 settings with the Migration tool. Now when I start D12 I receive the following error (and similar ones after that one). Apparently D12 tries to load packages from D11. Does anybody know why this is the case and how to fix it?

Happend to me too. I then deleted the registry branch for Delphi 12 under HKCU (not HKLM!). Delphi recreated it automatically on startup and then worked fine again.

Thanks Thomas. So the Migration Tool is buggy I guess. Is there already a QC entry for this ?

The Migration Tool has a special mode for migrating to a newer version, which requires to select the appropriate settings. Did you follow these when migrating? If yes and it didn't work, you should file a bug report.
