Problem with CAD application in wine

[Jeff Melville]

I'm trying to run a cad application in wine, and after finally resolving 
   all of my DLL issues, wine outputs this:

err:module:import_dll No implementation for 
shell32.dll.SHCoCreateInstance imported from 
L"C:\\WINDOWS\\SYSTEM\\avifil32.dll", setting to 0xdeadbeef
err:heap:HEAP_CreateSystemHeap system heap base address 0x65430000 not 
available
err:heap:HEAP_CreateSystemHeap system heap base address 0x65430000 not 
available
err:heap:HEAP_CreateSystemHeap system heap base address 0x65430000 not 
available
err:heap:HEAP_CreateSystemHeap system heap base address 0x65430000 not 
available
wine: Unhandled exception (thread 0045), starting debugger...

The splash screen of the app loads, and the main window is outlined but 
never gets painted before the exception.

My approach of importing native dlls for everything that it complained 
about seems to have run out... so how should I go about debugging it 
further?  I turned all debug messages on, but there was so much on the 
screen and slowed down loading so much I wasn't quite sure what to do.

Any help would be greatly appreciated. Thanks
