Can't use Microsoft Equation 3.0 on Word 2013 and Click-to-Run crash

Hi Cristian,

Let us start Word in application safe and then try inserting equations and check how it works.

To do that, press the ‘Windows + R’ key on the keyboard.

In the Run open box type in ‘Winword /safe’ and hit ok.

Note: There is a space between Winword and /.

If application safe works, you may disable the Add-ins associated with the application and check if it helps. For more information on the same, refer to the following link.

If issue persists, you may repair the Office 2013 installation and check if it helps in resolving the issue.

Follow the steps and let us know if that helps. If the issue persists, reply and we will be happy to help you.

Thank you.

I was attempting to use Equation 3.0 for the first time this summer earlier today.  The exact same issues that Christian experienced happened to me.  The same problem showed up in application safe that occurred earlier.  If I attempt to repair the Office 2013 installation, Office Click-to-Run crashes.  Has anyone determined a solution to this problem?

Equation 3.0 is GREAT.  I would not like to lose the ability to edit hundreds of old documents.

My work was offering Microsoft Office 13 at a discounted price earlier this year.  I downloaded it from the linked site (March 14?).  Equation 3.0 worked great right up until the end of June.  I did not attempt to use it again until yesterday, when I had the aforementioned problems.

The current version is 15.0.4631.1004

When I installed it, I most likely chose a traditional installation (if that option was given....I do not remember)

Please find enclosed detailed information about my computer, Windows and Office. I use HP EliteBook 8570w with Windows 7 Professional 64 bit with SP1. I use Office 365 four years long subscription. At the very end of December 2013 I downloaded Setup.X86.pl-PL_O365HomePremRetail exe file and installed it. Current version is 15.0.4641.1003 It worked without problems till the end of July. When I tried to edit some equations on 13 August instead of Equation Editor 3.0 (EE3) I had this strange and infamous message. One day later new upgrade was installed and problem disappeared. Yesterday there was next upgrade and I lost once more EEC. I am absolutely sure it is because of errors in upgrade. When I lost EE3 for the first time I looked into Microsoft Office 15 directory. Instead of EQNEDT32.EXE file I had BAK file. After upgrade from 14 August EXE file appeared. After yesterday’s upgrade there is no EXE file.

Actually, most Office installations are click-to-run these days. Do the following to find out: In Word, click File tab | Account. If you see an Update Options button, then you have a click-to-run version. To manually install the most recent update, click File tab | Account | Update Options | Update Now.

I do not think I should know differences between Click to Run and MSI versions in order to edit equations. But after many many years spent with computers and applications as university profesor I do understand what does in mean upgrade. According to MS Office information I have the definitely last version of Office. Sorry, screenshot is in Polish...
