"Failed to execute script" error in executable file created by innosetup

I created a simple script like the following.

This simply creates a text.txt file in the same location as the executable.

test.py

import os,sys
test_str = "test"

exeFileDir = os.path.dirname(os.path.abspath(sys.argv[0]))
path_w =  os.path.join(exeFileDir, 'test.txt')
with open(path_w, mode='w') as f:
    f.write(test_str)

And I created an exe file using Pyinstaller.

pyinstaller --noconsole test.py

At this point, running the exe file ran the code correctly and created a test.txt file.

Finally, I created a setup file using innosetup.

However, when I ran exe after running innosetup, I got the following error.

enter image description here

It seems that innosetup caused such an error. What caused it?

My innosetup configuration file is as follows.

; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!

#define MyAppName "testApp"
#define MyAppVersion "1.00"
#define MyAppPublisher "My Company, Inc."

Solution

  • "It seems that innosetup caused such an error. What caused it?"

    No, the error comes from the python script !! pyinstaller : Failed to execute script

    __ file __ is the name of the current file, which may be different from the main script if you are inside a module or if you start a script using execfile()

    Difference between --file-- and sys.argv[0]

    test.exe vs test.py

    os.path.abspath(sys.argv[0]) may fail if not also test.py is in the same folder as test.exe 

    exeFileDir = os.path.dirname(os.path.abspath(sys.argv[0]))

    To get the dirname of the absolute path, use

    exeFileDir = os.path.dirname(os.path.abspath(__file__))

    and now path_w should be correct 

    path_w =  os.path.join(exeFileDir, 'test.txt')
