Error: QuickBooks unrecoverable error Code 37760

Occurs: When importing into QuickBooks, QuickBooks crashes with error message Unrecoverable error and displays a dialogue with the error code 37760.

Cause:  Faulty QuickBooks interface file, affects queries to the Item and Employee lists. It appears that this error has been introduced into QuickBooks 2013 (US, CA and UK Editions) by the R7 release.  To see which release version of QuickBooks you have installed press the Ctrl and 1 keys simultaneously.

Resolution:  UPDATED 3rd July 2013.  Intuit have released R8 a new update that now resolves this issue, you can either get this in the update center or via automatic updates.  This may only initially be available for US users but we expect Canada and UK will follow shortly.
