2. How to Fix qlbcontroller.exe stops working?
If qlbcontroller.exe stops working on your PC, you can try several methods mentioned below to fix the issue.
2.1 Disable your antivirus software
Your antivirus software might be blocking the HP HotKey Support driver from running on your computer. This is especially true if you use third-party antivirus software. Therefore, it is strongly recommended to disable it temporarily before making any significant changes to the computer. The following steps may be different, depending on your antivirus program.
2.2 Perform a clean boot
There might be a third-party program or service preventing the qlbcontroller.exe from working. If that’s the case, you need to perform a clean boot to disable all the third-party services or programs running at the startup. Additionally, if the issue gets fixed after performing a clean boot, then simply look into the services or third-party programs to find the culprit. To do so, simply enable the services or third-party programs one by one until you find the culprit.
2.3 Reinstall the Hotkey Support driver
If nothing works, reinstalling the Hotkey Support driver should fix the issue, especially if there are any corrupted application files. If reinstalling the Hotkey Support driver also fails to fix the issue, you can use a system restore utility to go to the previous state where you were not encountering any issues. This requires a restore point to be created before you start encountering this issue. If you have created a restore point, you should utilize it to resolve this issue.
