What are AR3Thumb64.dll Error Messages?

Dynamic Link Library AR3Thumb64.dll Errors

AR3Thumb64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AR3Thumb64.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. ArtRage 5) could share the same AR3Thumb64.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 AR3Thumb64.dll is attempted to be loaded either when ArtRage 5 is starting up, or in some cases already running. Some of the most common AR3Thumb64.dll errors include:

Your AR3Thumb64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with ArtRage 5), or deleted by a malware infection. Furthermore, AR3Thumb64.dll file corruption could be caused from a power outage when loading ArtRage 5, system crash while loading AR3Thumb64.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.

CAUTION : We strongly advise against downloading and copying AR3Thumb64.dll to your appropriate Windows system directory. Ambient Design Ltd. typically does not release ArtRage 5 DLL files for download because they are bundled together inside of a software installer.
