If QuickMap displays the message:
QuickMap cannot read the registry HKEY_CLASSES_ROOT\QuickMap
This is because you do not have permission to be able to read and write to the registry. See your administrator for access to registry key HKEY_CLASSES_ROOT\QuickMap. Quickmap needs to be able to read and write to the registry in order to run. If this message is displayed, then usually it is because QuickMap has been run using a restricted account. Log onto your computer as an administrator.
