I've been trying to get Calibre for like 3 days now and every time the download finishes it says "This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows installer package" and im not sure who i have to contact, if its Calibre or Windows.. Has anyone else had this issue, if so how did you fix it?
