Why does this happen
Sometimes the F9 Com-Add in doesn't load properly or the user mistakenly disables it.
How to enable it
Please follow the below instructions
- Open Microsoft Excel
- Open a new Blank workbook
- Click on Add-Ins
- Select COM Add-Ins from the list
- Click GO..
Activating F9
- In F9 tab click License.
- Click on Activate.
- Enter the Activation Code and the click on Activate again.
If you do not have the activation code, login to F9 license portal here to get the activation code. F9 can only be activated once per user, so you will need to deactivate it on the portal first before you enter the code in excel.
