RuntimeError when running a Python executable created with auto-py-to-exe on a client’s machine

Question

We have developed a Dashboard in Python using the Dash library, which collects data via a Google Sheets API. To make the Dashboard accessible to our client, we converted our Python script into an executable file using auto-py-to-exe. This allows our client to use the Dashboard without needing to install Python or any additional libraries.

The executable runs perfectly on our own machines. However, when our client tries to run the executable on their machine, they encounter the following error:

Traceback (most recent call last):

Our client does not have Python installed on their machine, and we would like them to be able to use the Dashboard without having to install Python or any other dependencies.

We have tried to make him open the executable on and outside the OneDrive, but it didn't work. When we tried to make it work in one of my friend's computer, which didn't work in the first try, it started working when we compiled it in his computer. How can we make it work in our client's computer without him having to compile the code in his computer?
