Property: LEGACY_DATADIR_ONDISK, Signature:

In this scenario, the Quickmap Data Download Manager just hangs, then doesn’t let you proceed with the install.

This occurs because you have registered Quickmap 7, then installed Quickmap 8, which uses the Quickmap 7 registration – which is not supported by the Quickmap Data Download Manager.

To fix this, start Quickmap 8, then click Help -> Register Quickmap (or press F12) and register Quickmap. Try installing the Quickmap Data Download Manager again, and it should work after registering Quickmap 8.
