Word Not Saving Options

I have a situation where Word isn't saving any changes to options check boxes. For example, I'll uncheck the box for Word to replace normal quotes with "smart" quotes, but if I quit Word, the box is checked again.

Other Options save properly: I can create autocorrection entries, make changes to toolbars, customize keystrokes, and those save fine.

I've tried blowing away Normal.dot and starting from scratch, no luck.

I've tried restarting the PC. No dice.

I've tried starting Word in Safe mode, but the same issue occurs.

I ran diagnostics. No apparent troubles detected.

I've reset the appropriate registry key.

I've done a repair with the install disk.

I've uninstalled Word and reinstalled it.

Still, when I uncheck (or check) any check box in Word Options, after quiting Word I lose the changes. This doesn't happen in Excel or Outlook.

What else can I try?

I was able to solve the issue by disabling Add-ins. This is what finally worked:

First, I went to the MS Word icon IN THE MICROSOFT OFFICE SUBMENU in the Start/Programs menu. I right clicked the icon, choose properties, selected the Compatibility tab and checked the check box "Run this program as administrator."

Next I started Word, answered "Yes" when prompted.

In Word, went to Options, Add-ins, at hit the button at the bottom of the screen to manage the Add-ins.

I unchecked the Add-ins, confirmed changes, then restarted Word.

Now I could make changes the Word options and they saved.

Next I reapplied the Add-ins and unchecked the "Run this program as administrator" in the Word icon properties under the Compatibility tab.

It's a pain to go through all those steps to change options, but at least I know it's doable now.

Curiously, I have this same configuration on other computers (same Add-ins) and can save Word options with no problems.
