Bug ID: 56801
           Summary: Invalid path to UIAutomationCore.dll in the registry
           Product: Wine
           Version: 9.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

test app

I'm using the pywinauto library to perform some automatic actions in a GUI.
pywinauto, in turn, uses comtypes, which requires the location of
UIAutomationCore.dll to work. During this process, comtypes reports that it
cannot find UIAutomationCore.dll.

It turns out that, comtypes uses windll.oleaut32.QueryPathOfRegTypeLib (that
is, the QueryPathOfRegTypeLib from oleaut32.dll) to find UIAutomationCore.dll.

Wine 9.0 registry
[HKEY_CLASSES_ROOT\Typelib{8A9CA8EB-856B-43D9-ABD7-4A590054064F}\1.0\0\win64]
lists its location as "C:\windows\system32\uiautomationcore.dll\1",
while the path in Wine 8.0 is C:\windows\system32\uiautomationcore.dll.

Windows registry shows path as C:\windows\system32\uiautomationcore.dll

Can the correctness of this behavior be verified?  Should it be
"C:\windows\system32\uiautomationcore.dll\1" (\1 at the end) or is this the
wrong value?

I have attached a test application that reports the guid and path from the
registry.
