Bug ID: 46639
           Summary: LoadLibraryShim fails in wow64
           Product: Wine
           Version: 4.1
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: mscoree
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

The mscoree:mscoree 32-bit test fails on the tip when run in a 64-bit prefix:
mscoree.c:372: Test failed: LoadLibraryShim failed, hr=80070006
mscoree.c:385: Test failed: LoadLibraryShim failed, hr=80070006
> From a module log, it appears this is because it tries to load a 64-bit fakedll

for fusion.dll.

0009:trace:module:open_dll_file
L"\??\C:\windows\Microsoft.NET\Framework\v1.1.4322\fusion.dll" is for
arch 8664, continuing search
0009:warn:module:load_dll Failed to load module
L"C:\windows\Microsoft.NET\Framework\v1.1.4322\fusion"; status=c000007b

On Windows, there is a separate Framework64 directory which contains the 64-bit
fusion.dll.

I think fixing this will require updates to both mscoree and Wine Mono.
