Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
Each time I turn my laptop on, I keep getting the message I'm missing a trayapp.msi I cannot find the missing app on my system. Do I need to install a missing driver, if so which one?
> I'm missing a trayapp.msi I cannot find the missing app on my system.
It's some application that is trying to put an icon into your "system tray" -- the bottom row of your display.
The '.msi' is "Microsoft Installer" -- Windows has been told to run this "installer" program, to install some software.
If your computer is running fine, then you may choose to ignore the message.
> Do I need to install a missing driver, if so which one?
Open the Windows "Device Manager", and look for any "unknown device" or "yellow-exclamation-marks".
If that is what you see, then you really do have a missing device-driver.
Tell us what it is.
Double-click on that flagged item, and click "reinstall driver", and allow Windows Update to do a search.
