What are sync.log Error Messages?

General sync.log Runtime Errors

sync.log file errors often occur during the startup phase of BlackBerry Desktop Manager, but can also occur while the program is running. These types LOG errors are also known as “runtime errors” because they occur while BlackBerry Desktop Manager is running. Here are some of the most common sync.log runtime errors:

• sync.log could not be found.
• sync.log error.
• sync.log failed to load.
• Error loading sync.log.
• Failed to register sync.log / Cannot register sync.log.
• Runtime Error - sync.log.
• The file sync.log is missing or corrupt.

Most LOG errors are due to missing or corrupt files. Your sync.log file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BlackBerry Desktop Manager), or deleted by a malware infection. Furthermore, sync.log file corruption could be caused from a power outage when loading BlackBerry Desktop Manager, system crash while loading or saving sync.log, 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.
