How irritating does it seem when you are about to enjoy your favorite game or use an app but encounter the NotificationController.dll missing error? Though Windows is a comprehensive OS yet, due to functionality, the chances of errors are always there. DLL errors are also difficult to solve. Therefore, the first step is to know what causes the error and next about how you can resolve it.

What is NotificationController.dll?

NotificationController.dll is a Windows OS file that is located in the System32 folder. When it is loaded files like msvcp110_win.dll, msvcrt.dll, VEEventDispatcher.dll, api-ms-win-core-util-l1-1-0.dll or several other system files may get loaded. If one of these files is corrupted or missing, NotificationController.dll won’t be loaded and it could throw up an error.

There are several reasons responsible for the error. These include

• Temporary Glitch: Too much cache memory or programs running simultaneously interfere with your PC’s optimum functioning. This leads to errors like the missing DLL.
• Corrupted program or OS files: Due to multiple reasons, sometimes app installation or OS files can get corrupt.
