This article explains the BarTender error message “An error occurred while loading the document [document name and path]. Please try again. Details ‘6db132bc-a225-4ce8-8dfa-9c24fb754800’ was canceled” and details on how to fix the underlying problem.
This message indicates that the BarTender Print Portal is unable to locate a label design (i.e. .btw) file needed to print the selected label. There are likely several different situations that can lead to this message.
In the case that was brought to our attention, a restart of the server hosting the Print Portal corrected the problem. Perhaps there were changes to permissions that did not get rolled through IIS until the server was restarted. More research needs to be done to determine the specific cause.
