I use Microsoft 2007 and I have a problem when I use the Microsoft equation editor. When I type an equation many mathematical symbols ( ,-,.) do not appear on my screen. This problem is not related to the version of Microsoft office that I use because this problem doesn't occur in another PC with the same version. Microsoft Equation Editor 3.0 is no longer supported. Math Equations created using Microsoft Equation Editor 3.0 may not display due to absence of MT Extra font. To fix the issue download and install MT Extra font and restart the Office application.

I am having a weird issue with 2 of my workstations here. Both workstations are fairly new running Windows 7 Professional 64bit and Office 2013. When I attempt to edit a equation from Word 2013, I receive the following error message: 'The program used to create this object is Equation. That program is either not installed on your computer or it is not respond. To edit this object, install Equation or ensure that any dialog boxes in Equation are closed.'

The steps I've attempted so far:

1. Reboot the workstation
2. Ran the compatibility install provided by Microsoft
3. Tested on older versions of Office. (Works perfectly fine on Word 2010)
4. Different user profile with administrator rights
5. Checked for Equation, found in Insert > Equation (Drop down) > Insert New Equation (This worked)
6. Changing the documents format to older versions of Word
7. Trying multiple documents that have Equations (Same issue)

MathType 6.9 has added support for Word 2013. To insert Microsoft Equation 3.0 Go to Insert → Object → Microsoft Equation 3.0:

MathType has a trial version.

The messages referring to 'Equation 3.0' is shorthand for the 'Microsoft Equation Editor' which was an OLE component. It was a rebranded, cut-down version of Design Science's MathType editor. OLE components are small binary programs that are loaded into an existing process (usually office/'productivity' programs) which then display an inline UI. It was popular in the 1990s as a way to allow users to 'embed' content from other programs into Word documents, PowerPoint presentations, etc - this is what happens if you copy cells from an Excel spreadsheet and paste into a Word document, then double-click to edit it in-place. This technology eventually became COM (and COM+ and DCOM, led to the .NET Framework, and now is the basis for WinMD/WinRT in Windows 8 and Windows 10 - it's come a long way).

Anyway, because these components are binary programs in their own right, it means they must match the instruction-set architecture of the host process. If you're running 64-bit (AMD64) Office, then you need an AMD64 build of the Equation Editor.

..unfortunately, such a build does not exist (probably because it's too old and unmaintained to rebuild, or Microsoft doesn't have a license to the source code from Design Science anymore). So you'll need to use the 32-bit version of the Equation Editor, which only works in the 32-bit version of Office.

You can install the 32-bit and 64-bit versions of Office side-by-side, but I recommend instead creating a simple VM (virtual-machine) to install an older 'good' version of 32-bit Office to act as a format-bridge (Office 2010 is my personal favourite).

From within a 32-bit install of Office, you'll need to manually convert the Equation object to use Word's new Equation system - have fun, it isn't easy!

Microsoft Equation Editor 3.0 (MEE) was a third-party component that was included in many versions of Office to help users add math equations to documents. MEE was pulled from the product, retroactively back to Office 2007, due to security concerns. The modern, built-in, Office equation editor uses Office Math Markup Language (OMML) as the preferred format for equations in Office files.

You should convert any existing MEE equations to the OMML format if you want to edit them.

How do I convert an equation?

All you need to do to initiate a conversion is to double-click on your equation, or select the equation and press Enter. When you do that you should get a prompt that offers to convert this equation (and all other equations in this file) to the OMML format.

Note: You only need to do this on equations that were created in Microsoft Equation Editor.

Will my equation convert successfully?

In most cases the equation should convert just fine. You may see some formatting differences, like a slightly different font or spacing, and if you've used colors in your equation you may have to reapply the colors after conversion.

One exception is that the equation converter does not support long division. If your equation contains long division you'll probably want to recreate it rather than converting it from the old format.

I double-clicked but I didn't get prompted to convert my equation

If you don't get prompted to convert there are a few possible causes:

• The equation may already be in a supported format, such as OMML, and not require conversion. Pcunlocker download.

• The equation converter is only available for Office 2019 and Office 365 build 16.0.10730 or later.

  Tip: Not sure what build of Office 365 you have? See About Office: What version of Office am I using?

• Your file may be in an older format, such as .DOC, .PPT, or .XLS. Save your file in the modern, Office Open XML, format by clicking File > Save As (or Save a Copy if it's stored in OneDrive or SharePoint) and save a new copy of the file in the Office Open XML format (.DOCX, .PPTX, or .XLSX).

• If this file is shared, and other users are currently editing it, double-clicking the equation will open a dialog box that lets you know that conversion can't be done while multiple users are editing the file. Once the other users have exited the file you should be able to convert any equations.

How do I convert an equation?

The equation converter is only available for Office 365 or Office 2019. While your equations should still display correctly, in order to edit them you would need to either:

• Upgrade to Office 365 or Office 2019, then you can use the equation converter.

• Download and install MathType from Wiris. MathType has a free 30-day trial, after which you can purchase it if you still need it.
