Connect Domo to Salesforce

My company already has Salesforce, and that particular instance is connected to Domo.  Our company acquired a new company that has Salesforce which I am attempting to connect to Domo.  While attempting to do so, when I select to add an additional account the single sign-on kicks in and automatically reconnects me to the Salesforce instance we already have connected.  Do I need to install the Domo App Exchange within Salesforce at the new company or does anyone have any experience that could help recommend the optimal solution?

Thanks.
