Hello,
This error can occur when either Microsoft Excel is not installed, or the .Net programmability support is not enabled for Excel. If you have Excel installed, then you can follow these steps to enable the .Net programmability:
For Excel 2007:
1. Navigate to “Programs and Features” on your Windows machine (Control Panel > Programs > Programs and Features).
2. Open the Microsoft installer to modify Excel.
3. Make sure that “.Net Programmability Support” is checked, and click “Continue”.
For Excel 365:
1. Navigate to “Programs and Features” on your Windows machine (Control Panel > Programs > Programs and Features).
2. Select “Turn windows features on/off”.
3. Within this window, select “.NET framework 4.8 Advanced Services”, and click “OK”.
Please let us know if this does not resolve your issue.
Regards,
Katie
