You may get this error in Quickmap:
COM error Drawing file \\server\folder\file.ecw
Ensure that the file can be accessed from the location specified in the error. It could be that the file is missing or a permisison issue. This extends to the location of the file not being trusted (ensure the location is in the Trusted sites list), or the file itself may not be trusted (right click it and click Properties -> Unblock).
If this isn’t the problem, the file you are trying to load may be corrupt. Antivirus could also be a candidate for the root cause of the COM error drawing the file.
