What Does Error Code -6000, -80 Mean?

According to Intuit, Error Code -6000, -80: “An error occurred when QuickBooks tried to access the company file” has multiple possible causes.  Here are screen shots of the actual error:

QuickBooks 2009

QuickBooks 2007

The possible causes of this error are:

  • a damaged company (.qbw) file
  • in a multi-user configuration, multiple computers are configured to host QuickBooks (incorrect) instead of only 1 (correct)
  • in a multi-user configuration, security software such as a firewall is blocking communication with the QuickBooks server
  • attempting to convert a file (such as .qbb backup file) to a company file (.qbw) over a network rather than on a local hard disk

There are a number of troubleshooting steps to resolve this error that are discussed in detail in the Intuit knowledge base article linked below.  Before proceeding to those steps, insure that all computers in your QuickBooks installation have been updated to the latest QuickBooks release.  To verify the version and release of QuickBooks, press F2 while QuickBooks is running to display the Product Information window.  The Product field shows the version and release at the top left of the window.  In the example below, Premier Accountant Edition 2009 is the version and R3P is the release.  Complete this step on each computer in your multi-user setup.
