What are DEFAULTSTYLE.BIN Error Messages?

DEFAULTSTYLE.BIN Runtime Errors

Runtime errors are ACD/ChemSketch Freeware errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these BIN errors are triggered when DEFAULTSTYLE.BIN is attempted to be loaded either when ACD/ChemSketch Freeware is starting up, or in some cases already running. Runtime errors are the most common form of BIN error you will encounter using ACD/ChemSketch Freeware.

In most cases, DEFAULTSTYLE.BIN runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these DEFAULTSTYLE.BIN error messages mean that ACD/ChemSketch Freeware was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, ACD/ChemSketch Freeware will be unable to start without resolving these errors.

Finding the source of the DEFAULTSTYLE.BIN error is key to properly resolving these errors. Although most of these BIN errors affecting DEFAULTSTYLE.BIN will happen during startup, occasionally you will encounter a runtime error while using ACD/ChemSketch Freeware 2018.1. This can occur due to poor programming on behalf of Advanced Chemistry Development, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of DEFAULTSTYLE.BIN errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
