Fix: This app can’t be activated by the built-in Administrator

Windows don’t allow all levels of users to operate on the same level of security. While the administrators enjoy all the accessibility permission with a just click, it doesn’t hold true in the case of a standard/guest account on the system. But, sometimes even while using an administrative account, a user may see this “This app can’t be activated by the built-in Administrator” error message. Don’t worry. This is nothing but a simple misconfigured policy issue. Follow these steps.


Fix 1 – Make sure that you are using an administrative account

If you are using a standard account, you may feel this issue. You can change the account type or log in using an administrator account.

1. At first, press the Windows key+R keys together.

2. Then, type “control” in the Run and click on “OK“.

3. When the Control Panel opens up, tap on the drop-down beside the ‘View by:’ and set it to “Category“.

4. After that, click on the “Change account type” to alter the account type.

Fix 3 – Change the level of UAC

If altering the policy settings doesn’t work, you have to alter the level of User Account Control (UAC).

1. At first, press the Windows key and type “UAC“.

2. Then, tap on the “Change User account control settings“.


Uac Min


This will open up the User Account Control settings.
