Installing NI-VISA on M1 Mac with Monterey

[BSB@caltech]

HI

I am on an M1 Mac running Monterey.  I downloaded NI-NISA 21 for Mac and tried to install it.  I got the following error message:

“NI-VISA_Full_21.0.0.pkg” can’t be opened because Apple cannot check it for malicious software.

It Suggests donwloading a new version, Did this and got the same message.  How do I get the installer to run?

thanks

In menu bar, go to Apple -> system settings -> privacy and security. You will see the security warning and click "open anyway" to install the package.
