Each Bid Package is tagged with the version of On-Screen
Takeoff from which it was exported. In version 3.98.07 and newer, that tag is compared to the version of On-Screen
Takeoff into which a user is attempting to import the file. If the installed version is
higher, the import process will continue, if the installed version is
lower, the import will be denied. The recipient must upgrade to the same or higher version of On-Screen
Takeoff from which the export originated. See the
Product Information Page above for details on the current and previous releases of On-Screen
Takeoff.
