Pyscripter could not load a python engine ошибка

I have installed python but there is a error message «PyScripter could not load a Python engine» and when I click «OK» there is no python versions in registered versions AND unregistered versions…

You can add your python versions to PyScripter in that dialog. Just press the + key and select the directory that contains python.exe and pythonxy.dll.

PyScripter doesn’t come with python. You need to have some python distribution installed. Just remember:

The 64-bit version of PyScripter (x64) works only on 64-bit Windows and with 64-bit versions of Python. The 32-bit version of PyScripter works on both 32-bit and 64-bit Windows with the 32-bit versions of Python.

I downloaded python 3.7 (32bit) and attempted to load it in PyScripter, but got this same message. It’s placed in Unregistered Versions. Python 2.7 (32 bit) works fine.

Is this a standard Python distribution for python.org?
Are you on Windows 64bit?
Are you using PyScripter 3.4.2?

Yes, the 3.7 download was from python.org
Yes, I’m using Windows 10 Pro 64 bit
I can’t figure out what version of PyScripter I’m using?

It looks like I am using v3.4.1. I will try updating to 3.4.2.

I’ve updated to 3.4.2 and continue to see this message when attempting to switch versions.

What happens if you press the test button? Are you sure you have installed the 32-bit version of python 3.7? Enter the python shell and have a look at the top line.

Also check the registry. Does the key ComputerHKEY_CURRENT_USERSoftwarePythonPythonCore3.7-32 exist and does ComputerHKEY_CURRENT_USERSoftwarePythonPythonCore3.7-32InstallPath point at the correct directory?

I hit the test button for both versions of 3.7 you see in the screen shot and they are 32 bit.
Yes and Yes. The install path folder contents point to where I put them/where I set PyScripter to find them.

Strange. PyScripter works fine here with 3.7.0 and 3.71.
I see that is listed in the list of registered versions. Did you try activating what appears as registered version? You probably did and I guess activating that fails as well. (?).
If you open a command prompt, and issue

>Set do you see any python related variables? (PYTHONHOME or something similar)?

Yes, I tried activating both registered and unregistered. They both give you the same message.

Yes, I did get a whole bunch of variables after typing >Set.

This PYTHONHOME= looks very suspicious to me. Normally when an environment variable is empty it does not show. Try to get rid of it.

Windows 10 and Windows 8

• In Search, search for and then select: System (Control Panel)
• Click the Advanced system settings link.
• Click Environment Variables. In the section System Variables, find the PATHHOME environment variable and delete it.

I don’t see a PATHHOME variable in the Environment Variables menu?

In PyScripter in 2.7 I ran:
import sys
sys.path
Pyscripter is installed in Program Files (x86) folder. I’m on a x64 bit PC.

In Tools >> Python Path I noticed there was no path pointing to the 3.7 version. Do I need to add that path here?

I browsed to 3.7-32 in this window and the Added it. Then I closed out of PyScripter, opened it again and went to this same menu, but the path was no longer there?

• The Python path dialog is for temporary changes to the python path. Not useful here.
• In Windows 64 bit, 32 bit applications are installed in c:program files (x86). So it is normal that PyScripter 32bit is installed in that folder.

What might be causing the trouble is the PYTHONHOME (not PATHHOME) environment variable. If you look at the image with the output of the SET command it has a line:

PYTHONHOME=
This is indicates that the PYTHONHOME environment variable is defined with a non blank value (could be a space for example) .

What I told you above is to remove this environment variable. You can do so by following the instructions

• Press the Window button and type «Control Panel»
• In the Control Panel select «System and Security»
• In System and Security select System
• Click on «Advanced System Settings»
• In the dialog box «System Properties» click the button Environement Variables. Is there PYTHONHOME variable defiined there either in local or system variables?

It has to be since I cannot see any other way it would be listed when you issue the SET command. Delete it and start PyScripter again.

In addition or instead you can check the registry entries:

HKCUEnvironment
HKLMSYSTEMCurrentControlSetControlSession ManagerEnvironment

to see whether PYTHONHOME is defined there.

Yes, I ran through the environment variables but did not see PYTHONHOME=. And when I run >Set in the command prompt I’m no longer seeing PYTHONHOME=.

And nowhere in the registry did I see PYTHONHOME.

I am sorry. I am running out of ideas.

As you mentioned in the email sent to me, you are using the “Windows x86-64 embeddable zip file” Python distribution.  This Python distribution is for specific scenarios (embedding Python into an application) — see for instance https://stackoverflow.com/questions/37633550/python-embeddable-zip- and it is not (could not) be supported by PyScripter.   To use PyScripter you need to install Python in the standard way using an installer.
