Issue Details

I have installed the NI Package Manager. Previously I used it to install other NI software. However whenever I go to the "Browse Products" tab I get the following error message now:
There was a problem retrieving available products
Value cannot be null.
Parameter name: source
Please check your Internet connection and try again.


The machine NI Package Manager is installed on can access the internet with no issues. We have a company-wide proxy all internet communication passes through. As NI Package Manager can still updated itself and other installed software it seems that it can do so as well.


 

Solution

This issue can be the result of a proxy server that allows traffic to pass either with a login or without (also called non-authentication proxy), when your operating system has stored invalid and/or incomplete login credentials.

Follow these instructions to revise your settings:
  1. Open your Windows' Control Panel.
  2. Navigate to Credential Manager » Windows Credentials » Generic Credentials.
  3. Check if there is any credential record for your proxy server stored. It can either be under the proxy's IP address or its name.

Note: In this screenshot incomplete credentials to a local proxy are shown; the entry is missing a user name.
  1. Delete the invalid and/or incomplete record.
    • Note: Be aware that there might be another application relying on this record. That application will either create this entry again automatically or ask you to re-enter the credentials.
    • Be careful deleting credentials you don't know. You might have to contact your IT/Network Operations/admin to restore them.
  2. Restart the NI Package Manager.

Additional Information

NI Package Manager is a software to download, install, manage, and upgrade NI software like LabVIEW NXG. It also gives access to additional drivers, modules, and add-ons.

NI Package Manager is a different product than the VI Package Manager. The latter provides easy management and distribution of add-ons for non-NXG NI LabVIEW editions.
