This has happened to me twice now. I'm trying to install an OS X program (Halo to be exact), but the installer won't work because it says it can't find the OS 9 system folder. The problem is, I don't have Classic installed and I don't want it installed.

The last time this happened was when I first got this PowerBook and was trying to install AppleWorks from the CD. Same message. I've since had to send my PowerBook into Apple for latch repair, and therefore erased my drive and then reinstalled upon receiving the unit back. Both times this has been a problem has been within a few hours of reinstalling everything. The first time the problem magicall seemed to disappear. But since I have no idea why it went away the first time, I have no way of knowing how to fix it this time.

In both instances, it was a clean system, with no hacks, haxies, or system modifications of any kind installed. I've repaired permissions, logged out, and even restarted. Any ideas will be greatly appreciated.

I'm sure you're aware of Carbon applications that can be run both in OS X and OS 9, but just in case you're not... There are some applications that can be run in either OS X or OS 9, they're called Carbon applications (as opposed to OS X-only apps, called Cocoa apps). For these Carbon apps, if they've been written to run in both OS X and OS 9, you have an option whtether to run them in OS X or Classic. This is changed by getting info on the application in question and clicking or unclicking the checkbox for "Run in Classic environment).

Have you tried looking for that?

Just being written in Carbon does not make an app work in OS 9. There are many, many, many Carbon apps that are OS X only. For example, any Carbon app that is built as a Mach-O binary will not run in OS 9 (examples include the OS X Finder and the OS X version of iTunes). For an app to run in OS 9, it has to be built as a CFM binary, and even then, there are CFM apps that are OS X only, such as Word v. X.

Yep. I looked to make sure that it wasn't checked to run in Classic only. I even checked that option and then unchecked it.

However, I did find a solution. I dragged all the files on the CD, including the installer, onto my Firewire HD and installed from that. For some reason, the installer immediately worked without a single problem. So it appeared to be something with that particular CD. I even tried the AppleWorks CD that had originally given me trouble and even it worked.

Thanks for the ideas though.

I was aware of this but I don't think he needed that extensive of an answer. When I was writing my original post I did hink of the Word v.X / Internet Explorer example, as a matter of fact. CFM, eh? Cool.
