This is one of those Windows subtleties that catches people out from time to time.  In order to be able to put registry entries where they're required, the installer has to use an elevated permissions mode (essentially the same as using 'Run as Administrator').  Unfortunately, this does mean that drives mapped from Windows Explorer in the usual way are not recognised.


You have two options.  The instructions are based on a mapped drive letter 'H' but just substitute the letter you need.  If you browse to the network folder using the Windows browser accessible from the setup page, it will recognise the full network path, but this UNC network path is also what will appear in the path settings within the program.  Alternatively (see below), if you set up the drive mapping from a command prompt with elevated permissions, it will then be valid in the elevated permissions mode used by the installer.

Elevated drive mapping

You need to open a command prompt with elevated permissions by typing "cmd" in the search bar.  This should offer you the command prompt.  Right click on this to use 'Run as Administrator' which will open the prompt in the correct mode.

Now type this at the command prompt:

"net use H: <UNC network path>"

Where <UNC network path> is your network path beginning with the double slash (\\).

That should set up the mapping so the installer can recognise it.  Type "exit" to leave the command prompt.
