2019.10.2 LTS Excel Activities InterOp error and fix

Recently upgraded our Environment to 2019.10.2 LTS and started having issues with Excel activities. Here was the fix.

Upgrade the Excel Activities package to the latest version.
If you installed the StudioX Add-In it will need to be disabled as it will cause a fatal error (go to Excel COM add-in and unchek or delete add-in from Excel.)


can you give us more details? Saying you had the addin means you were using StudioX? Can you please give more details on the errors you had with the excel activities?
Thank you!
