When switching between company files using the QuickBooks File Open/Restore window or closing the company file with the X in the upper right-hand corner, you may see QuickBooks crash with an Unrecoverable Error (codes may change). You may also encounter this error when randomly working in QuickBooks (such as creating an invoice or going to payroll forms).
In some cases after updating a company file from a previous release, this issue can sometimes begin to occur. It is generated due to the company file miscalculating the number of open windows that were in your company file when it was updated.
Important: This issue has been resolved in the latest release for QuickBooks 2014. Ensure that your QuickBooks is up to date. If the issue persist, perform clean installation of QuickBooks.
