This is a continuation of TechNote 133…

If you have not first read and followed the steps in that article, please go to TechNote 133 and go through the process described there.

Please note: This article assumes you have confirmed you are using 64-bit Office. If you haven't verified this, don't just guess and don't assume. In fact, most computers running 64-bit Windows are not using 64-bit Office. They are using 32-bit Office. The steps below will not work for 32-bit Office.
  1. Launch Microsoft Word.
  2. From the File tab, choose Options.
  3. In the resulting window, from the left-side navigation menu choose Add-ins.
  4. Using the drop-down menu located at the bottom of the window, choose Word Add-ins and click the button labeled, "Go".
  5. In the resulting window, under Global Templates and add-ins, the following items should be present:
    MathType add-ins in Word
    Note: If you're using MathType 6.8 through 6.9d, the first item will be named MathType Commands 6 for Word 2010.dotm.
  6. If the items from the previous step are not present, proceed to the next step. If they are present, the "MathType Commands" item should be checked (selected) if you're using MathType 7 and later. If you're using MathType 6.8 through 6.9d, both items should be checked.
  7. If the items from step 5 are not present, that's OK. Please try this:
    1. Click the Add button. This will open a window titled Add Template.
    2. In the window, navigate to this path:
           C:\Program Files (x86)\MathType\Office Support\64
    3. You will see the following items in the folder (among others):
           MathType Commands 6 for Word 2010.dotm (if not using MathType 7 or later)
           MathType Commands 2010.dotm (if using MathType 7 or later)
           WordCmds.dot
      If there's not a …Word 2010.dotm file in the folder, verify once again you're using the correct version of MathType. Office 2010 64-bit is only supported by MathType 6.8 and later.
    4. Select one of them at a time, and click Open. This will bring it into the Add-Ins box. You will then need to click Add one more time to bring in the other add-in (either MathType Commands….dotm or WordCmds.dot).
    5. Once you have them listed under Templates and Add-ins, the boxes on the left side should have a checkmark inside, but if they don't, click to place a checkmark there. Click OK. (For MathType 7 and later, it's only necessary for MathType Commands 2010.dotm to have a checkmark.)
  8. This should restore the MathType tab in Word. Sometimes it takes a few seconds to load it in.
