SDK 2020.1 not working after Sage 50 2020.2 update


Our job control system exports invoices to Sage 50 (Canadian Edition) using the latest version of the SDK 2020.1. We had to update Sage 50 to version 2020.2. which includes the up-to-date tax tables. According to Sage Support, there won't be an update of the SDK and the 2020.1 SDK should still work. However, I receive the following error when I try to export an invoice:

The company file cannot be opened because it's version ( is not compatible with the application (

It seems I need an update for the SDK, but it isn't available online.

Any help would be highly appreciated.
