[CoE Starter Kit - BUG] ISSUE TITLE

[Akshit5-ui]

Does this bug already exist in our backlog?

• I have checked and confirm this is a new bug.

Describe the issue

In our environment we are facing issue with adding service account as system admin for all the environments with/without dataverse, it brings to the get role pop up but when I try to get role it simply gives error and asks to get role again after refresh.

Three issues due to this :

1. In continuation to this we are unable to upgrade Power Platform COE and deploy Copilot Studio Kit. The service account is intended to use in Power Platform Admin center to generate analytics about Data verse environments using Microsoft Power Platform Center of Excellence (CoE) Starter Kit. As a prerequisite the SRV account must be part of all the environments in Power Platform and must have the System Admin role for each environment to generate the analytics. (This sys admin role is not Entra role, but more specific to Dataverse environment)

We are unable to add the SRV as a member to the environment (Either manually or using Flow), although it is straight forward process and it should allow you to Get the Role by a simple click. However, the same operation is possible when we use our account.

2. The COE starter kit deployment also brings us to the roadblock of assigning system admin role for all environments which fails to happen as explained above.

3. In continuation to this, the Power BI Dashboard does not shows the correct data/information.

The service account has been assigned with permanent Power platform admin role. We have done upgrades in the past and never faced this issue. Also the current version that we are trying to upgrade the Power Platform COE Center of Excellence - Core components is 4.50.7.

Expected Behavior

In an ideal situation there should be a way to assign system admin role on all environments so that the administrator account can manage and collectively deploy solutions such as COE starter kit upgrade and Copilot studio kit deployment.

What solution are you experiencing the issue with?

Core

What solution version are you using?

4.50.7

What app or flow are you having the issue with?

COE setup Wizard

What method are you using to get inventory and telemetry?

Cloud flows

Steps To Reproduce

Once the solution for COE core components is imported for Power Platform environment, we use the play button to launch the installation wizard.
On the pre requisite landing page we see the error attached in screenshot.

Anything else?

Hi @Akshit5-ui ,
Thanks for the detailed information.

Setup Wizard – “Error loading control”
This issue occurs because the Creator Kit (which provides the PCF controls used on this screen) is either missing or was installed after the CoE Core Components. To resolve this, please follow the steps below:
Install the Creator Kit in the same environment:
https://aka.ms/creatorkitdownload
After installation, fully clear your browser cache.
Open the Setup Wizard again in an InPrivate/Incognito window or try using another browser.
Once the Creator Kit is installed and the cache is cleared, the pre‑requisite page will load correctly.

Unable to Assign System Administrator Role to the Service Account:
For Dataverse, the service account must meet the following requirements for the System Administrator role assignment to succeed:
It must be a user account (not a service principal/application).
It must have a Power Apps Per User or Power Apps Premium license
(Power Platform Admin role alone is not sufficient).
After assigning the license, please wait 15–30 minutes for synchronization.
Try assigning the System Administrator role again.

After completing both items:
The Setup Wizard will load correctly.
System Administrator role assignment will succeed.
You will be able to upgrade the CoE Starter Kit and deploy the Copilot Studio Kit.
Power BI inventory and analytics data will refresh correctly.

Thanks for the response, I will try the steps you mentioned above.

Just an FYI we have around 302 environments in sandbox production and 1200 for teams data verse. Assigning System Admin role individually is a big task and not possible. The account has power platform admin along with both licenses as you stated above. Tried post clearing browser cache in in-private browsing, getting same error.
The creator kit version is same as mentioned here https://aka.ms/creatorkitdownload , hence attaching screenshot.

Thank you

Hi @Akshit5-ui ,
Apologies for the delayed response, and thank you for the update.

Since the Creator Kit is already correctly installed and the issue still appears even after clearing the cache and testing in InPrivate mode, the next best step is to check whether the CoE Setup and Upgrade Wizard app has any unmanaged layers, as these can override the PCF controls and cause the “Error loading control” issue.
Please try the following:
Go to Solutions → Center of Excellence – Core Components
Open the CoE Setup and Upgrade Wizard app
Select … → See solution layers
If you see any unmanaged layers, please remove them using Remove unmanaged layer
Unmanaged layers are one of the most common causes of this control‑loading issue, even when all prerequisites are correct.

Regarding System Admin assignment across 300+ environments:
You are absolutely right — manually assigning the System Administrator role is not feasible at this scale.
Since the service account already has the required licenses and admin roles but still cannot be assigned the System Administrator role in any environment, this typically indicates a tenant‑level Dataverse user‑provisioning issue, rather than something caused by the CoE Starter Kit. The CoE does not assign or control security roles; it only relies on the underlying platform permissions.
