Bug ID: 47992
           Summary: msi:action tests fail when running them twice
           Product: Wine
           Version: 4.17
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msi
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

See the test results on the cw-*-64 machines, which are being run after the 32
bit tests:

https://test.winehq.org/data/tests/msi:action.html

This is due to the

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData$USER\Products\84A88FD7F6998CE40A22FB59F6B9C2BB\Features

key still being left after the tests. I'm not sure how to properly remove it.
Most machines are being reverted for every test run, so there it is not
visible.
