What are bdmainui.dll Error Messages?


Dynamic Link Library bdmainui.dll Errors

bdmainui.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like bdmainui.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Baidu Spark Browser) could share the same bdmainui.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 bdmainui.dll is attempted to be loaded either when Baidu Spark Browser is starting up, or in some cases already running. Some of the most common bdmainui.dll errors include:

Your bdmainui.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Baidu Spark Browser), or deleted by a malware infection. Furthermore, bdmainui.dll file corruption could be caused from a power outage when loading Baidu Spark Browser, system crash while loading bdmainui.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.
