Unable to Deactivate a Third-Party LabVIEW Add-Ons

Updated Jun 12, 2019

  • Data Ahead SP7 Toolkit for LabVIEW
  • Third Party Add-Ons

Issue Details

I need to deactivate third-party LabVIEW add-ons such as
  • SP7 toolkit
  • Spreadsheet Express by Aledyne 
When I try in Third-Party Activation Wizard, I obtain this error:

The add-on deactivation failed with the following message. Click Back to try again.
Function call contains invalid arguments


There are a couple of troubleshooting steps that could help solve the issue:
  • Third-Party Add-ons will need the developer of the add-on to enable deactivation functionality to be able to successfully deactive
  • Currently, activation for certain third-party add-ons is only available for LabVIEW 32-bit on Windows 10
  • If you need additional support for a third party Add-on check on the NI website who support the appropriate add-on
    • For example for this case, SP7 toolkit is supported from DATA AHEAD so you can write to sp7@dataahead.de
