Paraview 5.8 Mac installer

Hello,
We tried to install ParaView-5.8.0-MPI-OSX10.12-Python2.7-64bit.dmg using on a mac book pro with Catalina 10.15.6, but we get the error:
“There may be a problem with this disk image. Are you sure you want to open it?”

Is is something wrong with the dmg file?

Thanks for the help.

From what I can tell, the disk image is fine. I just installed ParaView to my new Catalina OS with this .dmg. I suspect that what you are seeing is a poorly written warning stating “I, Catalina, don’t know where this app is from. Be careful” or possibly “there are issues with the signing of this file”. Either way, it is fine.
