I have had a similar problems - says "Preference Pane must restart to access this" - like used to get with 32-64 bit switching - then just does nothing. Getting it with all sorts of panes - security - desktop.screensaver - but not all.

I think you might be having a slightly different problem. Go to Finder and open your applications folder. Right click on System Preferences and select 'Get Info.' Uncheck 'Open in 32-bit mode,' or something like that. That seems to be solving some problems of a similar nature.

I've had the same problem with multiple prefs panes not opening and indeed I found that System Prefs was operating in 32 bit mode. Changed to 64 and all cured. Many thanks.

Many thanks from me as well - also just solved my problem :-)

I have exactly the same problem - no idea how to solve it.
Just installed Mountain Lion this evening. I could access the pane.
Then after restarting, I couldn't.
First you get the 'not on an intel based mac' message, then the 'could not load' message.
What's the solution?!

Have had a call with Apple Support.
Deleting the com files for system prefs in the user library didn't work.
Just reinstalled OSX - didn't work either. Same error messages.
Awaiting another call!
Anyone else find a solution?

Still got nothing. I had also tried deleting the files to no avail. Good to know about the reinstall, though-- that was my next option!
Please do keep us posted about what you find out from Apple. Thanks!

is there still no solution to this problem? no word from Apple?

Still working on it - have a call with senior support today. Will report back.
Have also told them about this thread, so hopefully they'll be watching it.

I am having the same problem. Just upgraded to ML from Lion. 32/64 bits switch did not work.
Problems started when logging in to Twitter for the first time via Safari, and accepting the dialogue asking whether I wanted to make that Twitter account available for other applications. Now I can twit from the notification center, but cannot access Mail, Contacts & Calendars preference pane.
I assume it has something to do with Twitter plugin, but I have no clue on how to deactivate it...

I don't think it necessarily has anything to do with Twitter spectifically. I hadn't enabled my Twitter account yet when I first encountered the problem. In fact, that's one of the main reasons I so badly want to regain access to the Mail/Contacts/Calendars pane!

Same problem here.
Started to happen after setting up my Twitter account.
