I tried to install Scratch 2 under Linux for Education at school. I followed these good instructions to install Adobe Air - everything works fine. But if I execute the Air-Installfile for Scratch I will be asked for the root password. In the little Pop-Up-Window it's not working so I tried to start the Air-File with these:
/opt/Adobe\ AIR/Versions/1.0/Adobe\ AIR\ Application\ Installer /{absolute path to downloadfolder}/Scratch.air
It works fine, but I get an error saying error that my Scratch-Install-File is broken... I re-loaded again but nothing changed. Does someone has an helpful idea?
Look at your file size. The download have maybe been interupted before it was complete. It happened to me so I downloaded it again with a download manager like JDownloader and installed it successfully but only with sudo
sudo /opt/Adobe\ AIR/Versions/1.0/Adobe\ AIR\ Application\ Installer /{absolute path to downloadfolder}/Scratch.air
The problem is that you can't launch it directly when you installed it with sudo rights. I'm looking for a solution but this is another problem.
