uOverlay.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like uOverlay.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like Setup.exe - to follow. These files were created so that multiple programs (eg. Corel VideoStudio Pro) could share the same uOverlay.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when uOverlay.dll is attempted to be loaded either when Corel VideoStudio Pro is starting up, or in some cases already running. Some of the most common uOverlay.dll errors include:
- Access Violation at address - uOverlay.dll.
- uOverlay.dll could not be found.
- Cannot find C:\Program Files\Corel\Corel VideoStudio 2019\uOverlay.dll.
- Cannot register uOverlay.dll.
- Cannot start Corel VideoStudio Pro. A required component is missing: uOverlay.dll. Please install Corel VideoStudio Pro again.
- Failed to load uOverlay.dll.
- The application has failed to start because uOverlay.dll was not found.
- The file uOverlay.dll is missing or corrupt.
- This application failed to start because uOverlay.dll was not found. Re-installing the application may fix this problem.
Your uOverlay.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Corel VideoStudio Pro), or deleted by a malware infection. Furthermore, uOverlay.dll file corruption could be caused from a power outage when loading Corel VideoStudio Pro, system crash while loading uOverlay.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
