Anyone who has Studio One 2, or has activated Studio One 3 on their computer once, and then has changes their password in MyPreSonus may experience a login error when Studio One 3 either tries to activate or access their MyPreSonus account to authenticate the Product Key and credentials. This error may also occur while attempting to install Content.  

To fix, there is a way to reset Studio One 3 so that you are prompted to re-enter your credentials.

 NOTE: This information was recently changed, it is not necessary to remove the user.license file to resolve this issue. 

- This change can be done while Studio One 3 is running and when retrying the function that was failing previously, Studio One will then show a log in window.

- There's no reason to remove the license files or even restart Studio One.. 

1. Remove the password keychain information. 

Mac OS X Customers:

Mac: Launch "Keychain Access" application from the "Utilities" folder and delete the "Presonus_UserAccount" keychain.

Don't worry about removing the PreSonus_StudioOne_OAuth credential. 


Windows Customers:  

Launch "Credential Manager" application from the Control Panel / User Accounts and Family Safety, 

then find and delete the "Presonus_UserAccount" keychain.

Don't worry about removing the "PreSonus_StudioOne_OAuth" credential. 

Click on the downward pointing arrow in the little circle to open up the entry to find the link "Remove From Vault"

2. Launch Studio One 3 again and the program will launch.


3. You can now go back to the Studio One Install menu

The moment you click on any of the squares in the install list you will see this prompt:

Login with your MyPreSonus Username or Email address and your Password. 

Be sure to select "Remember My Credentials" and click Login to continue. 

4. install additional content without issue. 

If you don't check the "Remember My Credentials" check box, you'll need to login each time you access this menu. This is a matter of preference.
