Why installing at version 10.6.0? Even retail disk has been at 10.6.3 for a long time.

Make sure you go to Apple and download the Combo update.  If you download the 10.6.7 Combo update, it will update 10.6 to 10.6.7 in one step.  Remember to save any special kexts you might have installed in /S/L/E because the update might wipe them out.  You would need to reinstall them after the update but before rebooting.

I got the same problem over here. I have followed an AMD install process point by point. Come time to update, whether it be from 10.6.0 right up to 10.6.4, I get the same error. I have got the comboupdte from the apple site. I've tried under safe mode, bootcd, under nearly every boot flag I can think of. Still the same error. I've even been looking through most of OSX.net and Insanelymac and it doesn't seem if there's been many cases of this.

Anyone got an Idea, cause I'm out.

Two suggestions:

1.  When you get the error in the installer, hit Command-L to bring up the installer log.  It might give more details on the problem.

2.  Look into Pacifist from Charlessoft.  It can open PKG's and also install the contents.

In doing other research, some people had problems installing iLife and got the same error.  Turned out that a security certificate had expired.  Turning the date back to be within the certificate valid dates solved the problem.

I actually got it to work, today. I downloaded it again from http://support.apple.com/kb/DL1399 and it work straight away.
