Hello folks,

confirming, still present.

The installer/bootstrapper uses InstallShield out-of-process COM server
'IDriver.exe' and communicates with it using standard marshalling.

Half-way through installation:

--- snip ---
Wine-dbg>info process
 pid      threads  executable (all id:s are in hex)
...
 00000008 4        'Install_MP760a.exe'
 00000022 16       \_ 'IDriver.exe'
 00000068 1           \_ 'winemenubuilder.exe'
 00000061 1           \_ 'winemenubuilder.exe'
 00000054 1           \_ 'winemenubuilder.exe'
 0000004e 1           \_ 'winemenubuilder.exe'
 00000038 1           \_ 'winemenubuilder.exe'
 00000065 1           \_ 'winemenubuilder.exe'
 0000003e 7           \_ 'rpcss.exe'
...
--- snip ---

Installer displaying 'finished' dialog/button:

--- snip ---
Wine-dbg>info process
 pid      threads  executable (all id:s are in hex)
...
 00000008 4        'Install_MP760a.exe'
 00000022 16       \_ 'IDriver.exe'
 00000080 1           \_ 'MPDocSelect.exe'
 00000068 1           \_ 'winemenubuilder.exe'
 00000061 1           \_ 'winemenubuilder.exe'
 00000054 1           \_ 'winemenubuilder.exe'
 0000004e 1           \_ 'winemenubuilder.exe'
 00000038 1           \_ 'winemenubuilder.exe'
 00000065 1           \_ 'winemenubuilder.exe'
 0000003e 8           \_ 'rpcss.exe'
...
--- snip ---

After dismissing the 'finish' button, the parent process terminates and the
out-of-proc COM server is now orphaned:

--- snip ---
Wine-dbg>info process
 pid      threads  executable (all id:s are in hex)
...
 00000022 12       'IDriver.exe'
 00000080 1        \_ 'MPDocSelect.exe'
 00000068 1        \_ 'winemenubuilder.exe'
 00000061 1        \_ 'winemenubuilder.exe'
 00000054 1        \_ 'winemenubuilder.exe'
 0000004e 1        \_ 'winemenubuilder.exe'
 00000038 1        \_ 'winemenubuilder.exe'
 00000065 1        \_ 'winemenubuilder.exe'
 0000003e 8        \_ 'rpcss.exe'
...
--- snip ---

There is an 'oleaut32.ProxyIUnknown_Release' call on the server interface
before the final 'CoUninitialize' which should ideally allow the server to
terminate (instanciated with 'CoCreateInstance').

Interestingly if one cancels the main installer half-way through the install
process, the COM server terminates properly.
