Causes of QuickBooks Desktop Error QBWC1039

If a damaged QWCLOG.TXT file is causing the issue, then you should close out of QuickBooks and Web Connector completely, go to C:\ProgramData\Intuit\QBWebConnector\log and rename the QWCLOG.TXT file as QWCLOGOLD.TXT. You should then reopen Web Connector, restart your computer, and open QuickBooks again before logging into your third-party application.
