Frequently Asked Questions
What does Application Hang Event ID 1002 mean?
Event ID 1002 is an error logged by the Windows Event Viewer when an application, such as Microsoft Excel, stops communicating with the operating system and becomes completely unresponsive.
Can an excessively large file cause Excel to freeze and generate Event ID 1002?
Yes. Handling exceptionally large datasets, complex arrays, or volatile formulas on a system with limited RAM or processing power can cause Excel to stall, triggering an application hang event.

Will reinstalling Microsoft Office fix the Event ID 1002 error?
Reinstalling Office or performing an Online Repair is highly effective if the root cause of the freezing is a corrupted installation file, missing component, or damaged registry key.
