What are office64mui.msi.16.en-us.vreg.dat Error Messages?


Dynamic Link Library office64mui.msi.16.en-us.vreg.dat Errors

office64mui.msi.16.en-us.vreg.dat is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like office64mui.msi.16.en-us.vreg.dat, 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 Office 2016 Preview (32 bit)) could share the same office64mui.msi.16.en-us.vreg.dat 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 DAT 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 office64mui.msi.16.en-us.vreg.dat is attempted to be loaded either when Microsoft Office 2016 Preview (32 bit) is starting up, or in some cases already running. Some of the most common office64mui.msi.16.en-us.vreg.dat errors include:

Your office64mui.msi.16.en-us.vreg.dat file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Microsoft Office 2016 Preview (32 bit)), or deleted by a malware infection. Furthermore, office64mui.msi.16.en-us.vreg.dat file corruption could be caused from a power outage when loading Microsoft Office 2016 Preview (32 bit), system crash while loading office64mui.msi.16.en-us.vreg.dat, 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.
