The new Navigator (with Cloudflow) installer is similar to previous installers, but the Cloudflow installer is separate, launching automatically after Navigator completes its install. This will bring up a DOS console, showing that the CloudFlow application (and required services), are being installed. At the end of the install, everything should be operational, but if it isn’t, there are some options to try.
Failed to License issue
A common issue is that everything loads, but there is a breakdown in the licensing for CloudFlow. You should receive a licensing error when finishing the Navigator install. To resolve this, go to the folder containing the Navigator installers, and you will see a folder called “CloudFlow.” In this folder you will see a program called “InstallCloudflow.exe.” 
After launching this, it will bring up a console that gives you a choice to install, uninstall, or License. Type “L” and hit Enter. This should license the CloudFlow component successfully.
Install Cloudflow
If the normal Navigator install fails to correctly install Cloudflow, you can try to manually Install CloudFlow after the install. Open “InstallCloudflow.exe,” type “I” and hit Enter.
The first window will ask you where it needs to install a Viewer folder. The default location is: C:\Navigator\Navigator\Cloudflow.
This will then let you know that the install is processing. This will take several minutes, so do not worry, and try to force quit the installer. Let it run.
Next it will open another window, showing it is starting the Windows Services needed to run. Click Enter to close the window when prompted.
Lastly, the installer will license Cloudflow. Once this is complete, click Enter to close the installer.
Uninstall Cloudflow
Now, if you ever need to uninstall Navigator, likely Cloudflow will not be uninstalled. Navigator Uninstaller will attempt to remove all components, but it may be unable to remove the CloudFlow services. This may also make some files in the Navigator folder unable to be removed. You will have to use the Install Cloudflow.exe app to uninstall properly. This should remove the last components of CloudFlow, and let you delete the Navigator folder. A reboot may be required to remove the folder.
Launch the “InstallCloudflow.exe” program and type “U”, then hit Enter. This will bring up a File Explorer window, asking which Cloudflow Viewer folder needs to be removed. The default location is: C:\Navigator\Navigator\Cloudflow\Viewer
Now you will see a window stopping the Services, and removing them. After this is complete, you will be prompted to click Enter to close the top window.
Before the uninstall is complete, it asks you to remove a folder manually. Remove this folder, then hit Enter to proceed with the uninstall.
Once the uninstall is complete, you can hit Enter to exit out of the uninstaller.
