Unsupported disassembler issue

[DigiAngel]

Having just installed Python 3.7.7, using IDA v 7.4.191112 here what I get on startup with the plugin installed:

C:\Users\Me\AppData\Roaming\Hex-Rays\IDA Pro\plugins\lighthouse_plugin.py: Unknown or unsupported disassembler!
Traceback (most recent call last):

    raise NotImplementedError("Unknown or unsupported disassembler!")
NotImplementedError: Unknown or unsupported disassembler!

any hints on how to fix this? Thank you.

I just verified that Lighthouse works on Python 3.7.7, I think something is wrong with your install of IDA or you have conflicting versions of Python.

If you try to run this in IDA's Python console, I assume it will fail:

from PyQt5 import QtGui

This will show you the Python version:

import sys; print(sys.version)

I think you have two Python 3's installed on your box, and IDA is defaulting to the 3.8 install which does not work correctly with IDA 7.4 and Qt.

Please double check, and use IDA's idapyswitch.exe if necessary:

IDA's python console should be printing out the following:

Thanks...I only had the one python installed...had to run idapyswitch which looked exactly like the above with only one option to choose so...eh...who knows :)
