Check the status of Power-user in the application

• Click "File" at the top left of the application from where Power-user is missing (PowerPoint, Excel or Word)
• Click "Options" from the menu bar
• Select the "Add-ins" tab on the left

Look for the status of Power-user in the list of add-ins:

• Power-user shows as "Inactive"
• Power-user shows as "Disabled"
• Power-user is not listed at all 

If Power-user shows as an "Inactive" add-in, try to reactivate it

• In the drop-down list at the bottom of the page, select "COM Add-ins" (like in the screenshot above)
• Click "Go". The dialog box below will open:

• Check the "PowerUser"checkbox, and click "OK".

It can happen that the above procedure reactivates the add-in, but that it needs to be performed again every time PowerPoint / Excel / Word is re-launched. If you experience this, try to change the Load Behavior in the registry.

On the contrary, if the above procedure doesn't reactivate the add-in look at the below section What to do if trying to reactivate or re-enable doesn't work.

If Power-user shows as a "Disabled" add-in, try to re-enable it

• In the drop-down list at the bottom of the page, select "Disabled items"
• Click "Go". The dialog box below will open: 
• Choose "PowerUser" in the list of disabled items, and then click "Enable"

Sometimes, Power-user can stay Disabled even if you try to reactivate it. This may be preceded by PowerPoint hanging for a while on the splash screen, and then showing the error message: "PowerPoint is running into problems with the 'power-user' add-in", as show below: 

When this happens, you should try the steps described just below.

What to do if trying to reactivate or re-enable doesn't work

• Uninstall, re-download and reinstall Power-user
• Install the updated .Net framework Client Profile and VSTO

• Other add-ins might be conflicting with Power-user. Uncheck other add-ins from the dialog box above, and try again

• Try running the latest Antivirus updates, or temporarily disabling it and retry
• Make sure FIPS is not active on Windows on your machine
• Run the latest Service Packs for your Office version, which can be found from the Microsoft website.
• Make sure Microsoft Office allows add-ins on the computer (see below)
• Try repairing or reinstalling Microsoft Office on the computer (see below)
• Try to check Event Logs to get more information on the issue
• If nothing seems to work, reset the Windows user profile

If Power-user is not at all in the list of add-ins

If you cannot see Power-user at all in the list of add-ins from "File"/"Options"/"Add-ins", it means that the application (PowerPoint, Excel or Word) is not able to see that Power-user was installed.

Try uninstalling Power-user from the Control Panel, and then re-download it and reinstall.

If the issue remains, try repairing Microsoft Office on the computer (see below).

Further steps to consider

Allowing add-ins on Microsoft Office (for Office 2013 and earlier)
