How do I make "Profession" formatting work in Word Equation Editor

I read the question posted here:
https://learn.microsoft.com/en-us/answers/questions/5383724/equations-in-word
The second response from Microsoft talks about "professional" versus "linear" format. I've found that it frequently automatically switches an equation to linear, sometimes while you are adding other elements to the equation.

I followed the instructions, clicking on the equation, then clicking on Professional (in the right-click menu). This does not work - either before, during, or after editing the equation using the drop-down menus.
I recognize that there is a \tags solution, but I do not prefer this.

I would like to turn "Professional" on permanently for a Word document containing hundreds of equations... or at least be able to do it for each equation.

Comment: why would anybody want anything other than "professional"?? It is standard math notation; "linear" is not.

    Hi @Hole, John,

    Thank you for reaching out to us. I’d like to provide you with the following information:

    Based on my test environment, the right-click action and switching between Linear and Professional formats can be performed as shown in the image below:

    Version: 2510 (Build 19328.20266 Click-to-Run)

    If you are unable to switch between these two formats, please check the following:

    1. The formula is not in Equation format
      • If you are typing the formula as regular text, Word will not recognize it as an equation for conversion.
      • Only formulas inserted via Insert → Equation or using Math syntax can be converted.
    2. Currently in Math AutoCorrect mode but not switched to Equation
      • When you type a formula in the document without pressing Alt + = (to enter Equation mode), it remains as text.
    3. Word version or display mode is limited
      • Some older versions or Compatibility Mode do not fully support this feature.
    4. Formula contains invalid characters
      • If the formula includes special characters or incorrect syntax, Word will not be able to convert it.

    And if you want formulas to always display in Professional format, please set it up as follows: Click Equation → Conversion → Automatically convert expressions to professional format.

    The AI response said: "you can manually convert each equation to professional format using the right-click context menu".

    Doing this, choosing "Professional", does not fix the problem, either before or after creating the equation.

    I would like the limits of a summation to stay above and below the summation symbol, rather than auto-switching to the right.

    I would like fractions to stay above and below a horizontal line, rather than auto-switching to a diagonal line.

    I would like "professional" to work! Or for Automatic to turn off and stay off.

    To ensure that equations in Word are displayed in "Professional" format rather than switching to "Linear" format, you can use the following methods:

    1. Using the BuildUp Method: If you have already created an equation and it appears in linear format, you can convert it back to professional format by using the BuildUp method. This method is part of the Microsoft.Office.Interop.Word namespace and is designed to convert equations to a professional format.
         public void BuildUp();
      
    2. Preventing Automatic Switching: Unfortunately, there is no direct way to permanently set all equations to professional format for the entire document. However, you can manually convert each equation to professional format using the right-click context menu or by using the BuildUp method after editing.
    3. Using the Linearize Method: If you need to switch back to linear format for any reason, you can use the Linearize method, which converts an equation into a linear format.
         public void Linearize();
      

    While there is no option to set the default format for all equations in a document, using the BuildUp method after creating or editing an equation is the best way to ensure it appears in professional format.
