Hi

I am trying to install AIP Evolve via Marketplace on my Free Dev Teir.

I am getting the following error:

> This Marketplace install will result in the maximum number of action types allowed in this Ontology being exceeded. Please delete any unused action types to proceed

On the AIP Evolve Store in marketplace it says there are 66 total action types to be installed.

I have deleted all other action types in that given ontology/space.

What is the max number of action types available in the free dev tier for any given ontology/space?

Has anybody else (on the free dev tier) been able to install AIP Evolve? (via Marketplace?)

Is there a way that I can only install like 50 action types for a given Marketplace instal?

Hey @fdejoe123!

To answer your questions:

- The maximum number of Action Type in the dev tier plan is 60
- I don’t think there is a way to only install a specific amount of action types for a Marketplace product for now

Unfortunately, I don’t think there is a way to install AIP Evolve on a free dev tier plan since the application is reserved to **Enterprise** accounts.

Have a great day!

Hey both,

AIP Evolve is not available on DevTier at the moment. We are working to bring it to DevTier, ideally by the end of this year.
