I'm on OS 10.6.8 on a macbook air and trying to install the xcode 3.2.6 that i downloaded from apple. I have plenty of free disk space. When I run the installer I get the message: The Installation Failed. An unknown installation error has occured. I've tried installing from a new admin user. I'm not sure where to look or how to solve this problem. Any ideas?

    Before installing, be sure to quit:

    - iTunes

    - Xcode

    - Interface Builder

    - Application Loader

    - ...run Activity Monitor and kill iTunes Helper

    - download over a wired connection

    - confirm sufficient free space

    - don't install to any OS over 10.6.8

    Run System Profiler/logs and sniff around there...

     

    My opinion is that 50 GB is thin ice - you need to check your drive health via Disk Utility, empty trash and go for more.

    I'm confused how this is a good thing, having to reinstall the os?  that sounds a lot like what I used to have to do in windows world.   Truly it doesn't sound like a solution, only a fix.

     

    Or....

     

    Did you just reinstall ontop of your existing install without problems?

    I've sadly not been so lucky...

     

    i've reinstalled Snow Leopard, I've made sure none of the Apps above are running, I've tried to run the Terminal uninstall incase there were any old Xcode files on the HDD, but nothing, get the "Installation Failed" message each time I try.

     

    Seriously how can it be this hard to install?

     

    Is there something I'm missing?

    I've been trying to install xcode 3.2.6 on snow leopard off and on for a couple of days now. At each attempt I get the message: "The Installation Failed An unknown installation error...". The same message as in this thread.

     

    I first tried downloading a new installation package and got the same results. I then ran the disk utility to check for errors and cleanup permissions - I got the same results. I then reloaded snow leopard and updated it to 10.6.8 - I got the same results.

     

    I don't know where to go next. My macbook is one of the first with an Intel chip (Intel Core Duo) - my understanding is I can't upgrade to Lion so I seem to be stuck with xcode 3.2.6.

     

    Any ideas??

    I first just updated just mac os and tried the xcode installation, which failed. After some thought, I updated everything else (iTunes and such) and once again tried the xcode installation - this time it worked!! I'm in business.

    I updated my os to 10.6.8 via the combo update package then I experienced the problem described above.
    I checked the software updates and I only selected an update for the software installer.

    After a reboot I was able to install Xcode.
    I hope this will work for you guys.

    I was having the exact same problems and updating the Software Installer worked for me!  The Xcode installation worked like a charm right after that.  No need to re-install the OS!

     

    Thanks for all your help guys :-)
