The Configuration registry database is corrupt


This post is about an error that happened to an Desktop Bridge application that was published on Microsoft Store.

The following error was happening for machines with the Windows 10 build higher than 17763.55 and I could reproduce the issue in a machine with the version 1809.



The Configuration registry database is corrupt

It was happening because the App package had a file called user.dat in the root of the package that was causing the failure.

In this particular case, the user.dat file inside the package wasn't a Windows Registry file but a database file. This error started to happen after the launching of MSIX, that now has the User.dat and Userclass.dat files to capture the registry keys. Since the developer's user.dat file was not registry keys, Windows throw that error message informing that the registry is corrupt.

The reason the package works on the 1803 build of Windows is that Windows didn’t look for the existence of that user.dat file in 1803 – that check is a new feature (MSIX).

I hope that it helps.

  1. When the program says it is corrupted that mean it is pirated, or it can be damaged with viruses, or you give the maschine rong comando so it become error.

    1. In this case it is an error and the App is not launched. This error happens when the package contains a file called user.dat in the root. It didn’t happen until the 1803 build.
