"Certificate Verification Failed" Error

This is an error related to the Certificate Verification process for Smaart v8 and Smaart Di v2. It only impacts Windows computers and does not impact Mac OS. Note that if you are running Smaart v8.1.4 or older, you may see a more ambiguous "Danger, Will Robinson!" message instead. 

If you have updated to Smaart v8.5 and are seeing this error, please briefly connect to the internet the first time running Smaart. Afterwards, you can run Smaart offline. If you are unable to connect to the internet due to a restriction on your machine, then unfortunately the 8.5 update is not yet supported. Please send us a ticket so we can provide you with the Smaart v8.4 installer.
September 20th, 2021 Update: We have resolved this issue in our most recent update, v8.5.1 (as well as Di v2.2 and SPL 1.1). Please download the update either by opening Smaart and navigating to File > Check for Updates, or by downloading the new installer from your https://my.rationalacoustics.com account under the Downloads tab. Please do not deactivate the previous version of Smaart - you should not be required to reactivate. If any other issues occur, or if Certificate Verification Failed occurs again, please contact support@rationalacoustics.com for further support.


If you are running Windows 7 and receive this error after updating to v8.5, please note that you must first install the Windows 7 Service Pack 1 update. To check if the update is installed on your system (and download if it isn't), please follow this link to Microsoft's official support page.
