When you download RPR for Blender for macOS from the website and install it the 2nd installer dialog is blank.
The first dialog after beginning the installer is this:
![Install Dialog 1.png Install Dialog 1.png](/t5/image/serverpage/image-id/1674iB44EFA91D7D04349/image-size/large?v=v2&px=999)
The second dialog is this... I don't know what to press.
![Install Dialog 2.png Install Dialog 2.png](/t5/image/serverpage/image-id/1676i3F4471551D488258/image-size/large?v=v2&px=999)
This has been in every v1.7 installer for macOS and is still in the latest Mojave RPR 1.7.217 installer.
Mac setup:

This bug was happening in High Sierra 10.13.6 as well.
