Configuring NP-View Desktop

System Performance

NP-View Desktop is a resource intensive application.  For best performance, please ensure your system’s Power plan is set to High performance.

If you have administrator access, you can enable Ultimate Performance by opening the command prompt as administrator and copy paste: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 and press enter.

Windows control panel:


First Login

  • Upon first login, NP-View Desktop will require you to create an administrator account. Fill in the required information and click the “Create the NP-View administrator account” button. The password can be as simple or as complex as the user desires but needs to be at least 8 characters.
    • Local authentication is for users who wish to add an additional layer of protection. With this, the user can use whatever e-mail address and password they choose. If the user logs out of the system, the user id and password will be required upon subsequent application launches.  Otherwise, the session remains open and authentication is not required.
  • Read and accept the user agreement.
  • Next, you will need to enter your license key.  Once input, click the “Add license key” button.
  • Select your preferences for checking for automatic updates (requires internet access) and participation in our voluntary improvement program. Both selections use a slider that is default to off. To opt in, click the button and it will slide to the right. Click the save preferences button to complete.
  • Next click the get started button

User Menu

Access to the Help Center, License Manager, Update Manager and other administrative functions can be found on the User Menu located in the top-right corner of the Workspaces page.

License Changes / Upgrades

If you input a new license key from network perception, the user must log out and log back in for the changes to take effect. Note that the license key function is only available from the home screen (not from within a workspace).

Upload File Size Limit

NP-View enforces a maximum file size of 200MB by default. To change it, the config.ini file must be edited and the following row added:  MAX_IMPORT_SIZE=<size in bytes>. For example:  MAX_IMPORT_SIZE=209715200 which corresponds to 200MB.

  • Windows: the config.ini file can be found at:  ~AppData/Roaming/NP-View/config.ini
  • Linux: the config.ini file can be found at:  ~/.config/NP-View/config.ini
  • macOS: the config.ini file can be found at:  ~Library/Application Support/NP-View/config.ini

File Name Length Limit

The Windows desktop edition has a 50 character name length limit.  Files with names longer than 50 characters will fail to import.

Upgrading projects to workspaces

NP-View can import project files from previous versions of NP-View Java that were saved with configuration files.  Simply drag and drop a project file onto the Workspaces page and the import process will automatically begin. Alternatively, the user can create a new workspace and drag and drop the project file into the workspace. NP-View will parse the configuration files and render a new topology map (map locations from NP-View projects will not be imported).  Zone configurations with criticalities and access rule comments will also be imported. Note that NP-View workspace files cannot be loaded into legacy NP-View Java systems.
