When installing the Quickmap Data Download Manager (Quickmap Data Updater), you may get this error:
Quickmap Data Updater Setup
The installer has insufficient privileges to access this
directory: C:\Program Files (x86)\Custom Software
Limited\Quickmap Data Download. The installation
cannot continue. Log on as administrator or contact
your system administrator.
This can happen if you are running the installation file from within the zip file in which it was downloaded.
To fix this, copy (unzip) the installation file to a different location, then run it again.
