ABCUpload uses the Application Event Log to report important information.

• When the component is successfully registered or unregistered it will report this via an information event.
• If VBScript error logging is enabled (see Registry Settings) these will be logged as warnings.
• Serious errors or inconsistencies in the environment will be logged as errors.

For example if the component is unable to create a temporary file for caching uploads it will log an error "Unable to create Binary Read Cache". This kind of error will affect server performance but is not fatal.
