           Summary: msi: properly handle msidbComponentAttributes64bit
                    attribute to support x64 installers that mix
                    architectures in a single MSI package (32-bit and
                    64-bit components, filesystem, registry)
           Product: Wine
           Version: 1.3.1
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

Hello,

one of the main problems with current Wine msi is there are x64 installers that
mix architectures in a single MSI package: 64-bit and 32-bit components
(without a separate 32-bit installer for 32-bit components).

Basically 'msidbComponentAttributes64bit' is not handled.

Example: "mscoree.dll" -> .NET bootstrapper

"Component" table:

--- snip 32-bit ---
MSCOREE_DLL_____X86.3643236F_FC70_11D3_A536_0090278A1BB8   
{173A6EB3-6403-11D4-A53F-0090278A1BB8}   
DD_SystemFolder_X86.3643236F_FC70_11D3_A536_0090278A1BB8    8       
FL_mscoree_dll_____X86.3643236F_FC70_11D3_A536_0090278A1BB8
--- snip 32-bit ---

Attributes = 8

--- snip 64-bit ---
MSCOREE_DLL_____A64.3643236F_FC70_11D3_A536_0090278A1BB8   
{70B495DC-D747-4182-B6D7-86C8A2244B25}   
SystemFolder.3643236F_FC70_11D3_A536_0090278A1BB8 264   
FL_mscoree_dll_____A64.3643236F_FC70_11D3_A536_0090278A1BB8
--- snip 64-bit ---

Attributes = 264 (256 = msidbComponentAttributes64bit + 8)

When it comes to "InstallFiles" action:

The first extracted 32-bit version that gets (incorrectly) extracted to
system32 folder (remember: we're 64-bit install here) and subsequently gets
overwritten with 64-bit version later.

For the registry the same applies: In order to create registry values in 64bit
HKLM for components marked with "msidbComponentAttributes64bit" there is
nothing to change in 64-bit installs.

For 32-bit components (attrs < 256) the registry stuff must go to Wow6432Node.
Ideally Wine's msi should also support something like
"msidbComponentAttributesDisableRegistryReflection" to allow 32-bit components
to write into 64bit HKLM but that's not required for now.

Regards
