--- Comment #2 from Anastasius Focht <focht at gmx.net> ---
Hello denis,

this is the result of having both .NET Frameworks, 3.5 and 4.0 installed into
same WINEPREFIX.

CLRCreateInstance() is only available from CLR 4.0 or higher so this error is
kind of expected if the native 'mscoree.dll' is from .NET 3.x installation.

The proper way for application code to determine/request the correct CLR would
be:

1) load 'mscoree' dynamically
2) GetProcAddress() of 'CLRCreateInstance'
    -> if NULL, fall back to legacy path (CorBindToRuntimeEx)
    -> if non-NULL, call CLRCreateInstance() to get ICLRMetaHost
         -> if E_NOTIMPL, fall back to legacy path (CorBindToRuntimeEx)

Apparently the app wants CLR 4.x hosting and hard-binds to CLRCreateInstance()
(unsafe).

You could try to reverse the .NET Framework installation order to have CLR 4.0
mscoree: -> .NET 4.0 first and then .NET 3.x 

There might be some dialog boxes during install, stating 'failed to load
requested runtime'. You can dismiss them.

Regards
