The Installer must be run from a drive with a letter such as "G" and not from an explicit uniform naming convention (UNC) path. For example, you might have the MapInfo Pro DVD in your computer as USERSPC. Other users may share this device as USERSPC; however, it would not contain a drive letter. The MapInfo Pro Installation program requires a drive letter. To remedy this situation, map your network drive to a specific drive letter:
- In Windows Explorer, right-click the shared directory or DVD drive that contains the MapInfo Pro SETUP.EXE and select Map Network Drive.
- Choose a drive letter to map.
- Run the Installation Program again from the newly mapped drive letter.
