Method 1: Update all GPU drivers

The first thing you should if you’re encountering the CX_Freeze Fatal Error is to make sure that you’re using the latest graphics drivers available for your GPU. As various users have reported, this issue can occur in instances where a resource demanding application doesn’t have the required dependencies to successfully complete the process. Most of the time, this will happen because the computer is running with an outdated driver version.

In this case, updating the GPU driver to the latest using Device Manager or a proprietary utility should resolve the issue easily. Here’s a quick guide on how to do this:

1. Press Windows key + R to open up a Run dialog box Then, type “devmgmt.msc” inside the text box and press Enter to open up Device Manager.

2. Once you’re inside Device Manager, scroll down through the list of devices and open the drop-down menu associated with Display adapters. Then, right-click on the GPU that you’re using and choose Update Driver from the context menu.

   Note: Keep in mind that you’ll have multiple listings under Display Adapters if you’re having both a dedicated and an integrated graphics card. In this case, update both, but prioritize the dedicated GPU since that’s the one you’re going to

3. From the next screen, click on Search Automatically for updated driver software. Then, wait until the initial scan is complete, then follow the on-screen prompts to install the latest driver software available.

4. Once the newest driver has been installed successfully, restart our computer and see if the issue has been resolved at the next system startup.

If you’re still encountering the same issue, you can also try to go the proprietary route and update your drivers using a dedicated software. Device Manager is known for sometimes failing to identify the latest software version available.

Luckily, every major GPU manufacturer nowadays has developed a proprietary software capable of identifying and installing the latest graphics driver automatically based on your GPU model. If applicable, download and use one of the software below:

GeForce Experience – Nvidia
Adrenalin – AMD
Intel Driver – Intel

If the same issue is still occurring even after you’ve made sure that your GPU drivers are updated to the latest version, move down to the next method below.
