Windows 9x - Deployment
Hi,
I have successfully deployed a simple P4D-application on Windows XP systems.
When I run the application on Windows 98, however, it complains it could not
find "Python24.dll", although it resides in the same directory as the
executable.
Copying the .dll into C:WindowsSystem or System32 does not make any
difference either.
Any ideas?
Thanks,
-Andreas

Yes, try to set the property DllPath of TPythonEngine in the OnBeforeLoad
event:
PythonEngine1.DllPath := ExtractFilePath(Application.ExeName)
Hope that helps,

I had already set the DllPath property to the application directory for
testing purposes, with the same result: It makes no difference ...

Can you make sure that in the following
code:
procedure TPythonEngine.DoOpenDll(const
aDllName : String);
var
i : Integer;
begin
if UseLastKnownVersion then
for i:=
Integer(COMPILED_FOR_PYTHON_VERSION_INDEX) to High(PYTHON_KNOWN_VERSIONS) do
begin
FDLLHandle := LoadLibrary(PChar(GetDllPath+PYTHON_KNOWN_VERSIONS[i].DllName));
[…]
The expression in red is your expected
filename???
Maybe DllPath was not properly assigned
when DoOpenDll was executed?
Otherwise, try to write a simple Delphi app that would try to execute LoadLibrary with the
same information in Win98…
Bye,
Morgan

Hi Andreas
Hmmm...which 98 is it? First or Second Edition?
Could you run Dependency Viewer, http://www.dependencywalker.com/ on
your app? It shows the order in which everything is loaded, and the
paths, so it might give a clue!

I did. The path is exactly the same on both operating systems (XP + 98SE).

Hi Richard,
Windows 98SE (see the Dependency Walker log for more details). I created the
following console application:
######################
program Py9x;
{$APPTYPE CONSOLE}
uses
SysUtils, PythonEngine;
var
PyEngine: TPythonEngine;
begin
PyEngine := TPythonEngine.Create(nil);
PyEngine.PyFlags := [pfIgnoreEnvironmentFlag];
PyEngine.LoadDll;
PyEngine.Free;
WriteLn(`Done.`);
ReadLn;
end.
######################
It runs fine on XP systems, but fails with the same error "Python24.dll
could not be found" on my 98SE system. Here is the log file:

Morgan, excellent idea. It revelead msvcr71.dll was missing on the Win98 SE
system. If it is present, the console application runs fine.
Is msvcr71.dll bundled with any Windows 9x updates or newer version of
Office? It`s relatively small (340 KB) and can easily be compressed to less
than half the size (148 KB), still curious though.
Thanks for all your help, highly appreciated!
