I don't have a Windows 7 environment ready, but a couple of questions first. a) What .NET version do you have installed? b) Does pythonnet work for you? c) start Python and execute this commands. 

import clr

clr.AddReference('System.Windows.Forms')
clr.AddReference('System.Threading')

import System.Windows.Forms as WinForms
from System import IntPtr, Int32, Func, Type, Environment
from System.Threading import Thread, ThreadStart, ApartmentState
from System.Drawing import Size, Point, Icon, Color, ColorTranslator, SizeF

Does this work?

Thanks for answer! .net version is

execution of code your asked gives the saim error and it craches on just this

I have installed pythonnet from master brunch becose of 2.3.0 relsea gives install error I found issue where on that error was gived a recomendation to install pythonnet from master so I did it and got this error :) looks like it`s not problem in your modul, think can close this

r0x0r commented 5 years ago

As a workaround, you may try installing an older version of pythonnet. As far as I know pywebview does not rely on any pythonnet features that would require the latest version.

I am closing this issue now. If you find a resolution, please post it here for a reference.

I started issue on pythonnet page https://github.com/pythonnet/pythonnet/issues/772 and solve this error with installing .net sdk then got problems that MSBuild 14 no supported so I need to install MSBuild 15 (Visual Studio 17) with Win 10 sdk

@vanillycpp the installation for your platform (win7 32-bit) has been fixed in pythonnet
