Cannot open .dmg install package on macOS Catalina

I just downloaded the installer package on macOS Catalina (10.15.6). Then I double click on the Justinmind_Prototyper_MacOS.dmg file that was downloaded. The OS returns an error that it cannot open the disk image because there is a Resouce busy.

Perhaps the disk image is not compatible with Catalina.

Please advise how to install the application.

Hello,

Are you opening the disk image from Finder or a similar folder, or from within the Disk Utility app? If you've only tried Disk Utility, see how it works from Finder.

If you get the same result, click Apple men - Restart - and then test again. Let me know if this helps.

Thank you kindly,
