6 Fixes for Lightshot Not Working on Windows 11

Lightshot is a free screen capture tool available for Windows and Mac. You can grab screenshots, share them with others, or upload them to its cloud storage. It is even possible to annotate the screenshot. While it’s a fantastic utility, some users report that Lightshot is not working or doesn’t work properly and either crashes in between or doesn’t launch at all.

6 Fixes for Lightshot Not Working on Windows 11

Evidently, this happens when Lighshot doesn’t have administrator privileges, has a misconfigured hotkey, or is due to a recent Windows update. We will discuss six methods to fix Lightshot and make it functional again.

1. Restart Lightshot With Administrator Privileges

Missing administrative privileges can prevent Lighshot from saving images or working properly. So, you must restart Lightshot with administrative privileges. Here’s how to do it:

Step 1: Press the Ctrl + Shift + Esc keys to open the Task Manager.

Step 2: Find the Lightshot process and right-click on it. Select the End Task option.

Step 6: Go to the system tray icons and click on Lightshot. Or you can press the hotkey to open the capture window.

2. Check and Configure Lightshot’s Capture Key

Microsoft changed the way the PrintScreen key works in Windows 11. It opens the Snipping Tool by default now. Needless to say, if you previously used the same key to launch the screen capture in Lighshot, it won’t work now.

So, you must reconfigure the hotkey or disable the PrintScreen key from opening the Snipping Tool by default.

Here’s how to disable Windows from using the PrintScreen key for the Snipping Tool:

Step 1: Press the Windows key + I to open the Settings app.

Step 2: Click on the Accessibility option.

Check and Configure Lightshots Capture Key

Step 3: Scroll down to the Interaction section. Click on the Keyboard option.

Check and Configure Lightshots Capture Key 2

Step 4: Disable the toggle next to the ‘Use the Print Screen to open screen capture’ option.

Step 5: Close the Settings app.

Step 6: Go to the system tray icons area and right-click the Lightshot icon. Select Options.

Step 11: Press the PrintScreen key to check if the capture option appears now.

3. Change the GPU Preference in the NVIDIA Control Panel

A few users fixed the Lighshot not capturing issue by changing the GPU preference in the NVIDIA Control Panel. If you have a laptop with two graphics cards (integrated and discrete), you must switch to the auto-select GPU mode option in the NVIDIA Control Panel. Here’s how to do it:

Step 1: Press the Windows key to open the Start menu. Type nvidia control panel in the search bar and press Enter.

Step 2: Click on the Manage 3D settings option.

Step 3: Click on the Preferred graphics processor option and choose Auto-select.

Step 5: Close the NVIDIA Control Panel app.

4. Remove a Recent Windows Update

Many users complained about Lightshot not capturing screenshots after Windows installed an automatic update. However, some users noticed that the Lighshot problem disappeared after manually installing the latest definition updates.

All you need to do is open the Settings app and check for the latest updates. If any are available, install them and check if Lighshot works properly. But if there are no new patches and updates, you must uninstall the update that caused interference with Lightshot. Here’s how to do it:

Step 1: Press the Windows key to open the Start menu. Type uninstall updates in the search bar and press Enter.

Step 2: Find the most recent update and click on Uninstall.

Step 3: Click on Uninstall once again to remove the update.

Step 4: Restart your PC to apply the changes.

5. Update System Drivers

If you last updated your device drivers a while ago, you must update them using the Device Manager. Open the Device Manager and right-click on a device. Select the Update driver option, and the utility will install the latest drivers.

However, Device Manager doesn’t always download the latest drivers. In that case, you can use a driver download utility (MyAsus, MSI Center, etc) offered by your PC manufacturer. That will help you check and download all the drivers’ updates in one go.

For custom PC users, it will be painstaking because they need to check and download the latest version for each device. Also, update your BIOS along with the device drivers.

6. Reinstall Lightshot

The last resort is to reinstall Lightshot. Since Lightshot has no option to check for updates, you must uninstall the current version and replace it with the most recent version from the official website.

It will replace the corrupt files of the current installation and fix the launch and crash issues with Lightshot. Here’s how to do it:

Step 1: Press the Windows key to open the Start menu. Type appwiz.cpl in the search bar and press Enter.

uninstall lightshot

Step 2: The Programs and Features window will launch. Right-click on Lightshot and select the Uninstall option.

uninstall lightshot 2

Step 3: The User Account Control window will launch. Click on the Yes button.

Step 4: Follow the on-screen instructions to remove the app.

Step 5: Download Lightshot from the official website.

Step 6: Run the setup file and install Lightshot.
