“Easy Data Transform” can’t be opened because it was not downloaded from the App Store
You might see the error message below when trying to start the EasyDataTransform.app file for the first time:
Easy Data Transform is not in the Apple App store, but it is signed with an Apple digital certificate and notarized by Apple. It is safe to download, as long as you download it from our website.
You can fix this issue by setting (at your own risk) System Preferences>Security & Privacy>Allow apps downloaded from to App store and identified developers.
Then try to start EasyDataTransform.app again. Once it is working you can set System Preferences>Security & Privacy>Allow apps downloaded from back to App Store, if you wish.

And set System Preferences>Security & Privacy>Allow apps downloaded from back to the original setting (e.g. App store and identified developers).
4. Use xattr
Run the following (at your own risk) in a terminal:
xattr -d com.apple.quarantine <downloaded .dmg file path>
And then try to install from the .dmg file again.
