Mapped network drives are not visible during installation

Eric Updated by Eric

This article is related to installing software to a network using network drives with existing mapped drive letters.


During a network installation the software installer displays the 'Choose Destination Location' window.

Then the user clicks the Browse button to select a network drive to install the software to. But no mapped network drives are visible in the folder browser, so the installation has to be stopped.


This problem can be caused by many things, but the most common cause by far is a setting in the Windows Registry that prohibits browsing of a network environment under certain conditions.


Editing the Windows Registry is not something we recommend to regular users, so our software installer includes code that automatically edits the Windows Registry and corrects the problem.

Note: The only caveat is the software installer must successfully install the software one time on the affected computer. Since the software installer cannot see the mapped network drive, we have to install the software on the local computer first, then install the software to the network once mapped network drives are available.

Follow these steps:

TaxTools WorkShop

  1. Install the software as a single-user installation to the C: drive on the local computer.
  2. Launch the program and change it to Network mode, being sure to use a UNC path to connect to the network database. See: Mapped drives aren't visible

Other CFS Software

  1. Install the software as a single-user installation to the C: drive on the local computer. See: Software Locations (Default)
  2. Running through a successful single-user installation will ensure the Registry fix is made.
  3. Reboot the computer.
Important: A reboot is required for the Registry change to take effect, as the Registry setting in question is only referenced when the computer is booted and Windows started.
  1. Uninstall the software. See: How To Uninstall Software
  2. Install the software to the network. Mapped network drive should now be visible during installation.
