IDA has no python.exe but exists python64.dll, In such case how to specify the python path in settings.py?

[YuanBoXie]

IDA Pro 7.0 My setting.py is:

HOST = "127.0.0.1"
PORT = 7065
DEBUG_PORT = 7066
PYTHON = "C:\\Users\\97527\\.conda\\envs\\gemini\\python.exe"
LOGGING = False

But

C:\Program Files\IDA 7.0\plugins\idacode.py: No module named concurrent.futures
Traceback (most recent call last):

Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64 bit (AMD64)] 

How can I solve this problem?

I modified the tornado source code and skipped this issue. But Then I meet another issue: [IDACode] settings.PYTHON version mismatch, aborting load: [IDACode] IDA interpreter: 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40) [MSC v.1500 64 bit (AMD64)]win32 [IDACode] settings.PYTHON: 2.7.18 |Anaconda, Inc.| (default, Apr 23 2020, 17:26:54) [MSC v.1500 64 bit (AMD64)]win32 I can't find python.exe in the IDA Pro folder, I can only find python.dll and python64.dll, so maybe IDA interpreter: 2.7.13 is packed in this dll. In such a case, how can I specify the python variable in the idacode_utils/setting.py file?

[YuanBoXie]

Such a problem may be caused by IDA Pro 7.0. At this version of IDA Pro, It packs python env in python64.dll not pack python.exe, so I can't find python.exe to manually install the dependency. At the same time, I can't specify the python path in settings.py.

Is there anyone who install this plugin at version 7.0? How do you solve this problem?

In theory (I haven't tested this): It should be possible to use a "built-in" Python interpreter (as in, shipped as DLL), but it would require a lot of tweaking, and I'm not even sure if debugpy would support that properly. Your best bet is just getting an IDA Pro copy that introduced Python 3 (IDA Pro 7.4 and onwards), as these are best supported. Another thing you can try: Download idapyswitch.exe and see if you can force IDA 7.0 to use an external installation of Python, if that works it should solve all your issues.

Is there a specific reason why you're using IDA 7.0?

[YuanBoXie]

Thanks for your reply. Because I have some scripts written in python 2.7, IDA Pro 7.5+ can't use python2.7 so I tried to run this in version 7.0. But it seems this problem can't easily be solved. So I do as you say, I rewrite scripts in Python3 and upgrade the IDA Pro to version 7.5 then issue#35 can be solved.
