Bug ID: 39378
           Summary: winecfg and ntdll disagree upon the proper place for
                    DllOverrides key
           Product: Wine
           Version: 1.7.33
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: programs
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

I've run into this problem as I've tried to run a 32bit program in a 64bit
prefix that needed native msvcr120.dll due to missing (at very least) some
strto* functions.

When I've set the override via winecfg, they've got ignored till I've removed
builtin from /usr/lib32/wine.

Surprisingly, environment override *did* work without that step, so I've dug in
deeper - first via WINEDEBUG=loaddll, then WINEDEBUG="module,reg".

The conclusion was:

winecfg creates [Software\Wine\AppDefaults\foo\DllOverrides] keys
ntdll looks at [Software\Wow6432Node\Wine\AppDefaults\foo\DllOverrides]
keys

Obviously, ntdll trumps winecfg every time.

Correcting winecfg keys makes things work, but obviously, the entries disappear
from winecfg.
