Errors installing using Steinberg Download Assistant on Mac

I get an error every time I use the download assistant. It says it can’t open a file and to check permissions. I’m not sure how to check permissions. It doesn’t really seem like this is. the issue.

I’ve attached a screenshot. Anyone know how I can stop seeing these errors other than deleting the silly app?

Hi,

In Finder right-click to the file/folder and choose Get Info. Down you can see the Sharing & Permissions option. Double-check also all parent folders, please.
