    What I was trying to find is how to get into the equation editor that is part of Word 2003 which allows much more customization and other features that are important for the professional documents I write and edit. I have hundreds or maybe thousands of documents of my own and for the journals I’m involved with that were created with that other equation editor. I need to know how to access that while using WORD 2010.

    I can’t believe adding equation editor for Word 2007 is this difficult and convoluted. I waited 20 minutes locating instructions online and then trying to add the add-in. Microsoft is not very smart.

    Sometimes, the equation symbol is greyed out because your document in .doc file. You should try to save as in .docx

    I don’t even have “add/remove programs” on my control panel…

    I’ve got “programs and features” but can’t find anything related to the rest of these instructions.

    I’m using Windows 2007 as well. Theseinstructions seem like they are for and older version of windows. HELP.

  9. Madison says

    I tried this several times, and it is not working. The equation symbol is still grayed out in Word. Do you have any suggestions?

  10. ACB says

    Thanks for the information but I did all this, checked that my Equition Editor is set to run from my computer (and it is already), but the icon remains inactive on the Insert menu. Why?

  11. Pritesh says

  12. Andrew says

    Hi …

    You may be able to help me…

    My equation editor on my Word 2007 has suddenly disappeared. All my equations are looking like just empty boxes…

    Is there a way to fix this…

    Is this a problem with word 2007?

    Thanks for your help in advance

    Do you know a site which gives a whole bunch of key combinations for common math functions (ie. “ctrl + h” for exponent , “ctrl + i” for integral, etc.). If I can’t find them, that will extremely slow me down for equation editing, and I’ll probably switch back to office 2003.

    Thanks in advance.
