What are option.cfg Error Messages?

General option.cfg Runtime Errors

option.cfg file errors often occur during the startup phase of YS Flight Simulator, but can also occur while the program is running. These types CFG errors are also known as “runtime errors” because they occur while YS Flight Simulator is running. Here are some of the most common option.cfg runtime errors:

• option.cfg failed to load.
• Error loading option.cfg.
• Failed to register option.cfg / Cannot register option.cfg.
• Runtime Error - option.cfg.
• The file option.cfg is missing or corrupt.

Most CFG errors are due to missing or corrupt files. Your option.cfg file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with YS Flight Simulator), or deleted by a malware infection. Furthermore, option.cfg file corruption could be caused from a power outage when loading YS Flight Simulator, system crash while loading or saving option.cfg, bad sectors on your storage media (usually your primary hard drive), or malware infection. Thus, it’s critical to make sure your anti-virus is kept up-to-date and scanning regularly.
