1. Missing or broken DLL files: The “Class Not Registered” error can happen if the required Dynamic Link Library (DLL) files are missing or broken. DLL files are necessary for applications to work right, and if they are missing or broken, classes may not be registered correctly.
2. Incorrect or out-of-date registry entries: The Windows registry has important information about installed software and system settings. The “Class Not Registered” error can happen if the registry entries for a certain class or COM (Component Object Model) component are wrong or out of date.
3. Unregistered or incompatible COM components: COM components are small pieces of software that can be used over and over again. They let different programs talk to each other. The “Class Not Registered” error can happen if a required COM component is not properly registered or if the component is not compatible with the application that uses it.
4. Changes to default programs or conflicts: between programs trying to handle the same file type or protocol can cause the “Class Not Registered” error when trying to open or access those files.
