stop recurring crashes in Word and possibly Outlook View The Full Article Solution 32248 solves the immediate problem of word crashing, but what if the problem keeps returning First, do as 32248 says: 1: logoff close all Office apps and related plugins 2: logon 3: delete HKEYCURRENTUSERSoftwareMicrosoftOffice12.0WordData 4: start word Then, 5: go through the ribbon and run any 3rd party plugins like mathtype. 6: quit word and any plugins. Might need to logoff and logon again. 7: open regedit to the key HKEYCURRENTUSERSoftwareMicrosoftOffice12.0WordData 8: Rightclick on the Data and select Permissions. 9: Click advanced 10: Edit the current userand39s permissions 11: Select Set Value: Deny 12: OK Apply OK OK Now they cannot change their toolbars/ribbon, but at least it quits crashing. I suspect MathType may have something to do with this problem.
