What are cpprestsdk.dll Error Messages?


Dynamic Link Library cpprestsdk.dll Errors

cpprestsdk.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like cpprestsdk.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. Microsoft Project Professional 2016 (64-Bit)) could share the same cpprestsdk.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 cpprestsdk.dll is attempted to be loaded either when Microsoft Project Professional 2016 (64-Bit) is starting up, or in some cases already running. Some of the most common cpprestsdk.dll errors include:

Your cpprestsdk.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Project Professional 2016 (64-Bit)), or deleted by a malware infection. Furthermore, cpprestsdk.dll file corruption could be caused from a power outage when loading Microsoft Project Professional 2016 (64-Bit), system crash while loading cpprestsdk.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.
