I’ve been running Office 2013 in a virtual machine on my Mac for over a year, but suddenly the other day when I tried to open Word, I got the following error message:

1. Mac Cannot Open Microsoft Word After Restarting Mac
2. Microsoft Word Cannot Open File
3. Restarting Microsoft Outlook

• Nov 18, 2017 The first thought was to restart the device, and when I did that, the thing went south. Now, I was not able to open any app even the system app was not working. After a bit of Google search, I came across this forum which recommends restarting the Mac to safe mode and doing all kind of geeky stuff.

When you try to open corrupted document, Word will show a message like “Microsoft Word is not responding” indicating the problem. You can choose “Restart the program” option to cancel the current operation and try to reopen the file again.

Hmmm, of course I have a license! The product key was valid and it had activated fine over the Internet when I first installed it, so I wasn’t sure exactly why I was getting this error. Anyway, after playing around with a couple of possible solutions, it’s now running without the error message popping up. In this article, I’ll list out the various steps I tried to solve the issue and hopefully it will work for you.

Apr 16, 2018 When you try to open a Microsoft Word for Mac document, Word for Mac stops responding. Additionally, you may have to use the Force Quit command to exit the program.

Microsoft translator app. Note: You might get this message when using Office 2010, 2013 or 2016. The fixes below should work with any version of Office you have installed.

Method 1 – Change Time & Reactivate

One suggestion was to set the system time back to the date of the original install of Office, then re-enter the product key, activate the product, and then change the time back to the current date. So after you change the time on your computer, you can enter the product key by going to Control Panel –Programs and Features.

Now click on Microsoft Office and click on the Change button.

Now, check the radio button next to “Enter Product Key” and click on Next.

Now go ahead and find your product key for Office, which is usually on the packaging and type it into the box.

After you are done, you can launch any program in Office and do the activation. At this point, if it activated successfully, you can change the time back to the current date and time. It should stay activated even after restarting. If not, keep reading!

Method 2- System Restore

If Office was working fine and all of a sudden started having this problem, you can always try a system restore. You can get to system restore by click on Start and typing in system restore. You can also read more about how to use it here:

1. Type in services.msc in the search box and stop the service called Office Software Protection Platform.

2. Now go to C:ProgramDataMicrosoftOfficeSoftwareProtectionPlatform and rename tokens.dat to tokens.old.

Mac Cannot Open Microsoft Word After Restarting Mac

4. Now restart the computer and open any Office program. You’ll be asked to retype your product key and then restart again. Again open any Office program and you may have to type in the key one more time. It will then ask you to activate online and you’re good to go.

Method 4 – Uninstall & Reinstall

At this point, if you’re still having issues, then you may need to perform a full uninstall and reinstall and then reactivate Office. However, the way you want to do this is by properly uninstalling using the Microsoft FixIT tool. Make sure to download the version that corresponds to what you have installed.

You can uninstall using the Control Panel, but I would recommend using the FixIT tool since it really cleans out all the files, etc. It’s also a good idea to use something like CCleaner to clear out any left-behind registry entries after the uninstall. At this point, go ahead and try to install Office again using the original CD/DVD and then activate the product.
