start the application from the blender

How can I run my exe file from the blender?
I added a new panel, added a button to it, and when I clicked, I need to run the file.

import bpy
import os
import subprocess

path = “C:\myfile.exe”
path = os.path.abspath ( bpy.path.abspath (path) )
subprocess.Popen (path)

Here’s my code, what’s wrong? I can not connect the add-on even.

You can take a look at how I solved it in the Blender integration for LuxCore:

github.com

LuxCoreRender/BlendLuxCore/blob/master/operators/pyluxcoretools.py

import bpy
import os
import platform
from subprocess import Popen, PIPE, run
from shutil import which


class LUXCORE_OT_install_pyside(bpy.types.Operator):
    bl_idname = "luxcore.install_pyside"
    bl_label = "You need PySide. Install it now?"
    bl_description = ""

    def invoke(self, context, event):
        print("invoke")
        wm = context.window_manager
        return wm.invoke_props_dialog(self)

    def execute(self, context):
        threadcount = context.scene.render.threads
        install_command = 'sudo pip3 install --install-option="--jobs=%d" PySide' % threadcount

Your addon probably can not register because operator class names have to follow a specific naming convention.
Your operator class should be named “MESHT_OT_add_cube_sample” because of the bl_idname.

Indentation!

 
def execute (self, context):
    path = "C:\myfile.exe"
    path = os.path.abspath ( bpy.path.abspath (path) )
    subprocess.Popen (path)
    return {'FINISHED'}

Make sure you use forward slash (/) and not backslash ():
path = “C:/myfolder/myfile.exe”

By the way, it is totally pointless to post an error message in a language other than English without a translation.
