Bug ID: 42798
           Summary: MsiGetPatchInfoEx returns incorrect values for
                    UNINSTALLABLE, PATCHSTATE properties
           Product: Wine
           Version: 2.5
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: msi
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ArchLinux

On Windows, MsiGetPatchInfoEx for:

INSTALLPROPERTY_UNINSTALLABLE and
INSTALLPROPERTY_PATCHSTATE

returns a number converted to a string consisting of ascii digits (0x30 -
0x39).

On Wine, this function returns raw DWORD registry value.

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.
