ALL, I have a Mac with Snow Leopard. In order to compile and test my program I installed XCode from the original Snow Leopard installation CD. The version was 3.2. However, my client has Snow Leopard with XCode 4.2 and the program didn't compile, so I decided to remove old XCode and install 4.2.
I downloaded XCode 4.2 and then issued following:
sudo /Developer/Library/uninstall-devtools --mode=all
rm -rf /Develop
Then I tried to install XCode 4.2, but got an error:
An unknown installation error occured. The installer encountered error that caused an installation to fail. Contact the software manufacturer for assistance.
Does anybody know how can I fix it?
Thank you.
Found this posting, which fixed it for me as well. XCode installed without issues.
