When you try to upgrade Quickmap data, you may get this error:

Cannot Install Quickmap Data

Quickmap data upgrade cannot be run on a machine that does not already have Quickmap installed. Use QSetup.exe to install Quickmap before attempting to upgrade data.

[Cannot determine the Quickmap data directory location]

This will occur if you are running the upgrade from a computer that does not have Quickmap installed. This is because the upgrade requires the computers registry to contain a key that tells the installer where to copy the data to. To make the upgrade work, install it from a computer that has Quickmap installed.
