Common Causes of QuickBooks Crashing with Com Error
Before jumping into solutions, it's important to understand what causes QuickBooks to crash with a Com Error. Here are the main culprits:
Corrupted QuickBooks Installation: If QuickBooks files are damaged or missing, they may fail to communicate correctly with other programs, resulting in the Com Error.
