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?
MacBook Air, Mac OS X (10.6.8), 1.4 GHz Intel Core 2 Duo / 2 GB
This worked for me too. I changed my date to 1/31/12 (my certificate was expired too, I confirmed the error in my logs).
I had Xcode 4.3.2 installed. I uninstalled Xcode 4.3.2 to install Xcode 3.2.6. After installing 3.2.6, I will re-install 4.3.2. Apparently this is required if you wish to run both versions of Xcode side by side on Lion. I am following the instructions found here:

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??
