QuickBooks writes messages about what is happening in QuickBooks to a special log file, which we will call just "the log file:"
The log file contains QuickBooks messages, as well as information created by the Verify Data, Rebuild Data, and Condense Data utilities. It does not show General Protection Fault or Invalid Page Fault messages or messages or errors from other programs. New entries and errors are added to the end (or bottom) of the log file. The file includes date and time stamps with each log entry to help you identify the most recent entries.
Qbwin.log in Windows
Qbwin.log for Windows generates a separate Qbwin.log file for each version within each user. Each time you start QuickBooks, it renames the old Qbwin.log file and creates a new one.
Note: 'XX.X' represents your version of QuickBooks: 13.0 is Enterprise 13.0 and QuickBooks 2013 is 23.0.
Navigate to the following file path:
