Procore Integration with Catina: “App Installation Has Already Been Taken”

Overview

When integrating Catina (AIA Contract Documents) with Procore, you may encounter the following error message during setup:

“App installation has already been taken”

This error typically occurs before Catina can be fully accessed or configured within Procore, often when attempting to create or enable the Global Project Configuration. While frustrating, this is a known scenario and is usually related to how Procore is registering the app installation.

 

Why this error occurs

This message is generated by Procore and generally means that:

  

  • The AIA Contract Documents (Catina) app has already been installed or partially configured in your Procore company

  • A previous setup attempt was started but not completed

  • Another user or administrator may have initiated the installation

  • Procore is detecting the app as a duplicate installation, even though configuration is not finished

Procore allows only one Catina app installation per Procore company, and once that installation is “claimed,” Procore prevents additional setup attempts until the existing installation is resolved.

 

How to identify the issue

In a successful integration, the Procore App Configuration for Catina should show:

  • Global Project Configuration enabled and checked

If you are unable to access Catina within Procore and receive the error before reaching this configuration step, it indicates the app installation is blocked at the Procore level.

 

How to resolve the issue

Step 1: Confirm Procore permissions

Ensure the user attempting the integration is a Procore Company Admin. Non-admin users cannot complete app installation or configuration.

 

Step 2: Check existing app installation

In Procore:

  1. Go to App Management

  2. Locate AIA Contract Documents

  3. Review whether the app appears installed but not configured

  4. Identify which user originally installed the app, if possible

That user may need to complete the setup or remove the app so it can be reinstalled cleanly.

 

Step 3: Contact Procore Customer Support (most common resolution)

If:

  • The original installer cannot be identified

  • The app cannot be removed

  • The error persists despite admin access

You will need to contact Procore Customer Support to have them review and release the existing app installation.

How to contact Procore Support:

  1. Log in to Procore

  4.   

When contacting Procore, let them know:

  • You are integrating AIA Contract Documents (Catina)

  • You are receiving the error “app installation has already been taken”

  • The app does not appear to be fully configured (Global Project Configuration is not enabled)

Procore Support can clear or reset the app installation so the integration can proceed.

 

Important notes

  • This error is not caused by Catina

  • Catina cannot override or reset Procore’s app installation state

  • Once Procore releases the installation, the Catina integration can be completed successfully

FAQ

1. Why am I seeing the error “app installation has already been taken”?

This message is generated by Procore and means the AIA Contract Documents (Catina) app has already been installed or partially configured in your Procore company. Procore allows only one installation per company.

 

2. Does this mean Catina is already set up?

Not necessarily. Procore may register the app as installed even if configuration was never completed. In a successful setup, Global Project Configuration will be enabled.

 

3. Is this a Catina issue?

No. This error originates from Procore’s app installation system. Catina cannot reset or release the app installation in Procore.

 

4. How do I resolve this?

If you are a Procore Company Admin, identify who originally installed the app and have them complete or remove it. If that’s not possible, contact Procore Support to have the installation reviewed and released.
