Do you see an error code 0x80045C3C on the Xbox Live app for Windows?
The Xbox Live app for Windows lets users discover and download new games through Game Pass, play console games on their computers using cloud gaming, and connect with their Xbox friends.
This innovative service from Microsoft makes console gaming more accessible even for those who don’t own them.
Unfortunately, Xbox Live for Windows isn’t close to perfection just yet.
If you’ve been using the service for a while, you probably know that a few errors and issues can come up anytime. One of these issues is the error code 0x80045C3C.
When this error occurs, users are unable to log in to Xbox Game Bar and other applications that use Xbox Live service. Even when you’re using the correct credentials for your account, this error code simply prevents you from playing Xbox titles on your PC.
In this guide, we will show you how to fix the error code 0x80045C3C on Xbox Live for Windows.
Let’s get right into it!
1. Check Xbox Live Status.
If you can’t access Xbox Live on your Windows PC, it may indicate an issue with the servers. To confirm this, visit Xbox’s dedicated status page and check if there are ongoing outages on the service.
Unfortunately, server-related problems can’t be resolved on your end. In this case, the only thing you can do if the servers are down is to wait.
If the servers are up and running, proceed to the next solution below to troubleshoot the error on your end.
2. Restart Your PC.
Before changing your system configurations, try restarting your computer first if you can’t access Xbox Live. This way, you can ensure that the problem is not caused by a temporary bug or glitch in your system.
Check out the steps below to reboot your PC:
- First, press the Windows key on your keyboard to open the Start Menu.
- After that, access the Power Options tab.
- Lastly, click Restart to reboot your system.
Once done, go back to Xbox Live to check if the problem is solved.
3. Update Windows.
The current version of Windows you are using might not be compatible with Xbox Live. On the other hand, it’s also possible that there’s an issue with your system that triggers the error code 0x80045C3C.
Whichever the case is, follow the guide below to update your system:
- On your keyboard, hit the Windows + I keys to open Windows Settings.
- Next, scroll down on the side menu and click on Windows Update.
- If there’s an available update, click on Download & Install.
After updating Windows, restart your system and check if the problem is solved.
4. Scan for Corrupted Files.
If the update does not work, you can try manually scanning for corrupted system files on your computer. Unfortunately, you cannot expect Xbox Live to function correctly if your operating system has an issue.
See the steps below to use SFC on Windows:
- First, access the Start Menu and look for ‘Comand Prompt’.
- Now, click on Run as Administrator to launch CMD with administrative privileges.
- Inside the CMD, type ‘sfc /scannow’ and hit Enter.
Once done, try accessing Xbox Live again to check if the error code 0x80045C3C still occurs.
5. Reset the Xbox App.
The installation package of the Xbox app on your computer may have gotten corrupted, explaining why you can’t access its features. If this is the case, you can always reset the app through Windows Powershell.
Here’s what you need to do:
- Press the Windows key on your keyboard to access the Start Menu.
- Next, look for Windows Powershell and click on Run as Administrator.
- Finally, enter the command below and hit Enter.
Get-AppxPackage -name “Microsoft.XboxApp” | Remove-AppxPackage
Restart your system afterward and check if the Xbox app is now working.
6. Check Your Network Connection.
A slow or unstable internet connection could also trigger the error code 0x80045C3C on Xbox Live. When accessing Xbox Live services, you’ll need stable internet, especially if you’re planning to play on the cloud.
To check if your network is the problem, run a test using Fast.com to measure its current upload and download speed.
If the result shows that your network is the problem, reboot your router to re-establish the connection with your ISP’s servers. Unplug your router from the outlet and wait for 5 to 10 seconds before reconnecting it.
Once done, perform another test to check if the problem is solved. If your network continues to run slow, contact your provider and ask them to fix their service.
7. Update Your Network Drivers.
Another reason for slow internet connections is faulty network drivers. If you’re struggling to access any online service or game on your computer, it’s possible that your network drivers are broken or corrupted.
Check out the steps below to update your network drivers:
- First, press the Windows + X keys on your keyboard to open the Quick Menu.
- Next, click on Device Manager.
- Expand the Network Adapters tab and right-click on your network controller.
- Lastly, click on Update Driver and follow the prompts.
Restart your system after the update and check if the problem is solved.
8. Reinstall Xbox Live.
If you still can’t access Xbox Live due to the 0x80045C3C error code, we suggest reinstalling the app on your computer. This way, you can ensure that you have the latest working version of Xbox Live.
See the steps below to uninstall Xbox Live:
- Access Windows Settings on your computer.

- Finally, locate Xbox Live and click Uninstall.
Reinstall the app afterward and check if the error code still occurs.
