--- Comment #1 from tblodt@icloud.com --- This test creates registry keys in HKEY_CLASSES_ROOT and tests the code that retrieves values from those keys, and it fails because HKEY_CLASSES_ROOT is not writable without elevated privileges.
It could instead put the keys in HKCU/Software/Classes, which is writable without elevated privileges, but then the tests would fail on Wine because IQueryAssociations doesn't check there. That's a different bug. I plan to send a patch to fix it and another patch to make the tests run without elevated privileges.
