Why am I seeing the error: Service Unosquare passcorepro (passcorepro) failed to start. Verify that you have sufficient privileges to start system services at running the installer?
Breaking changes were made in version 1.3.5 if you are updating from a previous version you need to clean the installation folder, to be more specific, delete the appsettings.json before running the new installer.
How to fix the "RPC server is unavailable. (Exception from HRESULT; 0x800706BA)" error?
This error is caused by a common issue with the connection to your AD, read more about it in here.
Can I customize the visual appearance of the app?
Yes! passcorepro is a total customizable app, inside the admin app we added a section called Web Application, inside there's a form called Branding, here you can customize the app and see a preview of how will look.
