Serviio Installer can't be installed on this disk 1.5.2 Mac

"Serviio Installer can't be installed on this disk"
Previously, I had 1.5 version (no issues)
I tried everything:
[*]Permissions is OK
[*]Daemon disabled in Terminal
[*]Application trashed and cleaned
[*]Server removed
sudo rm -rf /Library/Application\ Support/Serviio
sudo rm /Library/LaunchDaemons/org.serviio.server.plist
And still no luck
Looks like the 1.5.2 Installer corrupt, Please FIX
and meanwhile, where can I download the previous versions?
