For example, if "Uninstallable" property has a DWORD value 0 in registry, Windows' MsiGetPatchInfoEx returns '0' (ascii digit 0x30), but Wine's implementation returns a null byte (0x00).
If necessary, I can send some C code demonstrating the bug.
That would be nice. Note that we already have tests for MsiGetPatchInfoEx in dlls/msi/tests/patch.c. It shouldn't be hard to add some.
