Config Wizard Errors

Hi,. I’m not very savvy when it comes to technology but I can follow instructions. I have done everything to a T to do a add-on for my Kodi app on a Windows system. Keep getting an” error on Config Wizard check log files” when I try to go into it. Well go into log files and it says error downloading. So then I go delete everything I had previously done try adding it again and same results. Any type of step by step help to figure this out would be mighty helpful and appreciated. Thank you in advance. P.s. if this isn’t allowed on this part of the forum and I need to go elsewhere just let me know.
