What does “Class not registered” error on Windows 10 mean?
Basically, it is a pop-up error message that usually appears when somebody tries to access jpeg. or png. images or some other format of images, Microsoft Edge, Internet Explorer, and Google Chrome. This error pops-up due to unregistered DLL file of Apps and programs.
When a DLL file becomes unregistered then this type of error occurs. A DLL file (Dynamic Link Library) is a type of file that contains necessary instructions for all other programs about how to perform some certain operations. The data allocated to a single file can be shared by multiple programs simultaneously. That’s why it is called “dynamic” because the data is used only as per the requirements. Unlike all other executable programs (with .exe file extension),.DLL files can’t be run directly. Other code must be required that is already running. Apart from this, DLL files have the same format as .exe files and even some may use the .exe file extension.
So this error “Class not registered“ occurs only when a .DLL file becomes unregistered. It can affect any software. In this guide, I will try to explain to you how to fix this error by applying different working solutions.
