Community Edition 2021SP1 for Mac .dmg "is damaged"

[nekomati2]

I'm trying to install LabVIEW Community Edition 2021SP1, but opening the disk image file gives the message 'LabVIEW2021SP1Community.dmg is damaged and can't be opened.'

If I try to verify the dmg from Disk Utility I get this:

The checksum on the download page matches the result I get with MD5 in Terminal for the downloaded file. My Security and Privacy preferences are set to 'allow apps from App Store and identified developers' and I've tried opening via right-click as well as double-clicking. I've tried the same thing on three different Macs running Catalina, Big Sur and Monterey respectively, downloading the dmg separately to each one, with the same result - the first and last of those have successful previous installs of Community Edition 2020.

What am I missing?

I have the same problem. Even though I can open and mount it through disk utitlity, it still throws errors when installing...
