Hi guys, I'm new to this group so hopefully I have posted this in the correct forum.
I have been using Calibre for years without any issue however a few months back it went weird (cannot even remember what it did ) and I uninstalled it and tried to reinstalled it. Unfortunately it will not reinstall and comes up with the error above. I have tried doing it many times all with the same result. I am using a Windows laptop. I would appreciate any help
