Can't install adobe reader on my macbook (Catalina 10.15.5)

[ThomasHeintzelmann]

When I try to install the downloaded file - I get the error message: 

“AcroRdrDC_2000920063_MUI (2).dmg” is damaged and cannot be opened. Move it to the bin. (“AcroRdrDC_2000920063_MUI (2).dmg” er beskadiget og kan ikke åbnes. Du skal flytte det til papirkurven.)

I also tried special installation, informing the istallation assistant that I'm on a Intel 10.15 mac. Nothing seems to help. Can any of you please help me?
