I downloaded the Jalview Installer for OSX but the install application won't run


Jalview is free to end-users because of support from the UK's BBSRC and The Wellcome Trust

Thank you all those who have already written such nice letters!

The OSX InstallAnywhere version of Jalview is downloaded as a ZIP archive (install.zip) which is normally unpacked automatically to create an application called 'install' that you can run. If nothing happens when you double click the application, then there are a few things that could go wrong.

Installer doesn't launch because it was unpacked with a third-party archive tool

If you have chosen an alternative archive program for OSX to use to unpack ZIP files, then it probably didn't set the executable permissions for the application after it unpacked it. The easiest solution is to right or option click the install.zip that you downloaded, and choose 'Open with -> Archive Utility (10.X)' (where X is the numeric version of OSX that you are running); this will create a new 'install' application (probably called 'install 2') that you can now launch.

If using a different archiver doesn't work, or you are working from the console, then you need to delve into the installer's application directory. Open the console, cd to the directory where the install application is located (probably ~/Downloads), and type:

  chmod u+x install.app/Contents/MacOS/install
  open install.app

Permissions problems result in an error shown in the OSX Console window that reads something like

([0x0-0x6a86a8].install[25620]) posix_spawn("/Users/jimp/install.app/Contents/MacOS/install", ...): Permission denied
