Bug ID: 52441
           Summary: Soft-Denchi DRM fails to register UCX.ocx
           Product: Wine
           Version: 7.0-rc5
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: advapi32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

This software is required by some games (e.g. Armored warrior iris).

To test it install MFC42 and MSVC 2008 SP1 runtime to 32-bit prefix and install
Soft-denchi, then run "regsvr32 UCX.ocx" in C:/Program Files/Soft-Denchi.

I tried to understand why it fails. Maybe someone more knowledgeable can
find/understand the root cause:
> regsvr32 UCX.ocx

it starts loading UCOpgDlg.dll

... call some crypt functions ...

call crypt32.CryptBinaryToStringA with flag CRYPT_STRING_HEX
03e8:fixme:crypt:CryptBinaryToStringA Unimplemented type 4

call advapi32.CryptExportKey

... call some more crypt functions ...

call advapi32.CryptVerifySignatureA
 -> returns NTE_BAD_SIGNATURE and EXCEPTION_WINE_CXX_EXCEPTION is thrown

...

03e8:warn:module:process_attach Initialization of L"UCOpgDlg.dll" failed

...

regsvr32: loading UCX.ocx failed (it was localized error message)
