wine users - May 2010 - Toolbook problem?

Hi
I'm running an application that uses toolbook files such as 
tb70net.exe and others.
winevdm.exe crashes leaving a long logfile starting with:

wine: cannot find L"C:\\windows\\system32\\TB70.exe"
mario at arrayan:~/.wine-bottles/Pipo/drive_c/Program Files/Pipouni>

In 16 bit mode.
Register dump:

(continues with other 170 lines of info)

The file TB70.exe is nowhere to be found. On the CD hosting the
application there are several files TB70XXX.EXE  (XXX=many things),
but no TB70.exe ... Somehow windevdm.exe expects to find tb70.exe on 
C:/windows/system32 (the wine version of this).

Any help please?

Thanks
Mario
