Symptoms

"Page doesn't exist" error is presented when clicking the Configure link for the App on the Installed Packages page.

Solutions

In the latest version, we've included a Lightning Setup Wizard, which requires that My Domain is enabled in the Org. Please make sure you have that configured. More information on how to set My Domain up can be found here.

After My Domain has been configured, please make sure the following has been done:

1) The user needs to have access to the Email to Case Premium LEX tab in their profile.  So under Assigned Apps in the user's profile, make sure 'Email to Case Premium (E2CP__Email_to_Case_Premium_LEX)' is set to 'Visible.'

2) Under Object Settings in the user's profile, ensure the setting called 'Email to Case Premium Setup' is set to 'Default On' instead of 'Hidden.'
