    I've got some system preferences that require I launch System Preferences into 32-bit mode. At least that's what I'm assuming, because every time I try opening them System preferences says it must quit and reopen to work. I press OK, it quits but doesn't reopen automatically. When I reopen it nothing happens.
    So, I clicked on get info for the system preferences to change it to 32-bit mode but realized that I don't have the option. For some reason, there's no check mark for 32-bit mode. I've included a screenshot. Can anyone explain why?

    What preference panes are you talking about?

    The ones I have, that require to run SP in 32-bit, automatically restart SP in 32-bit, after asking me to do so.

    Are you booting into the 64 bit kernel? If so, 32 bit stuff isn't going to run.

    Please stop spreading this bit of misinformation. 32 bit apps run fine on the 64 bit kernel.

    Did you run Xslimmer or another app that strips Universal Binaries down to the Intel-only code? The Get Info window for System Preferences says it's Intel only, not Universal, but on mine it says it's Universal, and I have the option to launch in 32-bit mode.

    If you did, afraid you'll have to Archive and Install, and don't do that again unless you know exactly what you're doing and the consequences.

    Unless that application is using a 32-bit kext.

    Right. That's pretty rare though (thank goodness. kexts are... risky).

    Ah, thanks Mal. You were right. Silly mistake on my part. However, I was able to remedy the problem by compressing\copying System Preferences.app from another computer and pasting it into my applications folder. All is fine now.
