Hi!
  Thanks, it's really what the program was checking for!
  Now the installation proceeded and even succeeded without a glitch!
  However, the installed program doesn't run :-(.
  
  It requires to start the service first. The following occurs:

patrol at arcus:~/.wine/drive_c/SYSD$ wine Sysd.exe -1 -start

StartServiceCtrlDispatcher starting;
This will take several seconds or more.  Please wait. Use arg -help.
err:advapi:service_control_dispatcher failed to create pipe, error = 0
StartService: the StartService function failed. SYSD Service 1.
  File not found (0x2)
fixme:advapi:RegisterEventSourceA ((null),"SYSD"): stub
fixme:advapi:RegisterEventSourceW (L"",L"SYSD"): stub
fixme:advapi:ReportEventA (0xcafe4242,0x0001,0x0000,0x00000001,(nil),0x0001,0x00000000,0x7fc8fd14,(nil)): stub
fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0000,0x00000001,(nil),0x0001,0x00000000,0x7ff6c970,(nil)): stub
err:eventlog:ReportEventW L"CmdStartService: The StartService function failed."
fixme:advapi:CloseEventLog (0xcafe4242) stub
OpenService:
patrol at arcus:~/.wine/drive_c/SYSD$

  After the first err: from advapi (failed to create pipe), the program really
waits for about a minute and then writes the rest in a quick row.
  Is there a chance it will run in wine in a near future ? May using
native advapi for NT4.0 help ?

  I'm also answering one of the former questions: No, the program cannot
be downloaded from anywhere; it's a part of commercial software which is
bought together with an EWSD telephone exchange.

  Many thanks for Your support!
                           With regards, Pavel Troller
