Hi Jorma,

Here is some info about the search order of .DLL's:
http://msdn2.microsoft.com/en-us/library/ms682586.aspx

Since you say it extracts the files into a Temp folder,  I'm guessing
that it should add this Temp Folder to the Path (for 98 anyway...).
Is it possible that the Path has grown too long,  or that you are out
of environment space on the Win98 system?  If so the Path maybe has
been truncated,  Or maybe it fails to modify the Path,  and that is
the problem.

The error message says that it cannot find the file.  If a file really is
there,  I'd wonder if it can't find it it because the Path isn't
pointing to it.  In the other OS'es it may be using the other search
mechanisms available in order to locate the .DLL.

If this isn't it,  it's probably time to run it under a debugger
(IDLE, GDB, or other),  set some breakpoints,  run to just before
where things break,  and then single step along and see what's really
going on,  at the moment when things do break.  And which .DLL is
involved,  as that might provide a clue.
