This only affects one of our customers, so it’s a fairly rare issue but you may be seeing this if you use Access 2010.
After installing the November or December updates for Access 2010, you may encounter a crash while performing a text file import/export.
The crash occurs if you click on the *Advanced* button within the Import/Export wizard. The fix is to remove these two patches.
November 10, 2015, update for Office 2010 (KB2837592)
