Evan, would you be willing to provide msi installation logs so those on the forum can determine the specific issue causing the failure?

Here are the instructions for 'Enabling MSI Logs': Generating and Locating NI Package Manager Error Logs

Evan, NI Package Manager prevents two installation related transactions from occurring at the same time and the message you are getting suggests that Package Manager thinks this is the case. A simple fix should be to reboot the system and they try the installation operation again.
