Troubleshoot: The installer does not see the network path (mapped drive)
Edited
If the installer does not detect the network path, it may be due to a change in how Microsoft handles mapped drives.
Instead of using the mapped drive letter, use the server name (UNC share) in the installer's network path field. For example, instead of "Z:\GA-Taxpro", use "\servername\GA-Taxpro".
note: It is recommended that you do not allow the installer to create a desktop shortcut automatically. If you do, the shortcut will contain the server name instead of the mapped drive letter. If you need a desktop shortcut, create it manually after the installation is complete.
