What steps will reproduce the problem?

1.Using Delphi 2010 install P4D from SVN (Python_2010.dproj)

2.Drop a PythonEngine VCL into a form

3.Modify the attribute to match 2.7 python version (DLLPATH: C:\python27,

DLLNAME: python27.dll, RegVersion: 2.7 and uncheck UseLastKnownVersion )

4. Execute the application

What is the expected output? I expect to see the application running with an

empty form.

What do you see instead?

---------------------------

Error

---------------------------

Error 193: Could not open Dll "python27.dll"

---------------------------

OK

---------------------------

and after ...

---------------------------

Error

---------------------------

Python could not be properly initialized. We must quit.

---------------------------

OK

---------------------------

Application just quit.

What version of the product are you using?

Delphi 2010 update 5

On what operating system?

Windows 7 x64

Are you sure your python27.dll is in the C:\python27 directory? In all user

installations it is placed under c:\windows\system32.

In any case just leave the DLLPath blank, unless you use an unregistered

version of Python.

Cannot reproduce here.

• Changed state: Invalid

I've copied the file from system32 to C:\python27 because it wasn't there ...

even tried with the dll in the test application folder.... empty PATH or not it

doesn't want to load any python dll. Have you tried with Windows 7 x64 ?

Clearly there's something fishy with the method of loading the dll... maybe

this has changed with the new OS.

Oh! Windows x64!  You need to install Python 32 bit since Delphi does not

support x64 yet.

again!!

Thank you very much! It works with python 32 bit.

Also, it would be great to advise in your wiki about this issue. I know that we

can't load 64 bit dlls with 32 bit application but i was focusing instead on

your error code. The whole day i've searched on google for :

 Error 193: Could not open Dll "python27.dll" or Python could not be properly initialized. We must quit.

It would be great to remind people that they might installed earlier before

trying P4D, that a x64 version of python and is not compatible with delphi and

p4d.

Wish you eternal success with P4D

have a nice day

laurent
