I have tried 3.2.5, 3.2.6, 4.0.2, 4.2 etc and I get an install error immediately after providing credentials. I provide username, password. I am admin. Then I get The "Installation Failed" error:

An unknown installation error occurred. The installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.

How can I find out what the problem is?

  • Yes, that's very weird issue. I don't use SL anymore, but saw that download when looking for something else and remembered it as it is something that I haven't seen before. – lupincho Apr 11 '12 at 6:32
  • "The installation failed" :( Even after this update. I tried to install Xcode 3.2.2 on Mac OS X 10.6.8. – Benny Neugebauer Sep 14 '13 at 11:51
