We can’t display component 'flowruntime:lookup', because it isn't supported in Classic runtime. Ask your Salesforce admin to distribute this flow in Lightning runtime instead.

Hi there,

I'm getting the following message: We can’t display component 'flowruntime:lookup', because it isn't supported in Classic runtime. Ask your Salesforce admin to distribute this flow in Lightning runtime instead. but I have already enable the setting in process automation settings so I'm not sure what else I'm missing. Any help would be greatly appreciated.

Hi Kimberly,
Are you launching any lightning component through the Flow?

Hi Danish yes I am launching a lightning component in the flow specifically it's the new lookup component that was recently rolled out.

Hi Kimberly,
According to the error, I am thinking you are running the flow in classic.

Hope this issue is resolved. If not, I found a solution online:
Enabling "Enable Lightning runtime for flows" on process automation settings, fixed this issue for me.

I am having this same issue. 

Were you able to resolve this?

I am experiencing the same issue, even though, I have enabled Lightning runtime for flows on the process automation settings.

The solution is here: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_flows_lightningruntime.htm
  • Create a Lightning app that declares a dependency on the lightning:flow component.
  • Add the Lightning Components for Visualforce JavaScript library to your Visualforce page using the <apex:includeLightning/> component.
  • In the Visualforce page, reference the dependency app.
  • Write a JavaScript function that creates the component on the page using $Lightning.createComponent().
