Send to Excel with Equations

I'm trying to send a cash flow series from a sample project in SAM to excel with equations, however, I get an error saying this version of SAM cannot export with equations - how do i go about correcting this / which version do i need to be downloading

The "Send-to-Excel with Equations" feature is available for the residential, commercial, and single owner financial models, but not for the partnership flip or sale leaseback models.

Only the Windows version of SAM can interact with Excel, so the feature is not available at all for the OS X and Linux versions of SAM.

To explore the details of all of the financial models in Excel, see the relevant workbooks on the SAM website Financial Model Documentation page .

Best regards,
Paul.
