Hi,
I tested downloading link of Spire Barcode with IE and Chrome, but it worked well on our side.
We provided you with another downloading link. Welcome to try the link
http://www.e-iceblue/downloads/spire.barcode_1.1.1.zip to download the latest version of Spire.Barcode.
If there are any questions, please feel free to contact us.
Best regards and have a nice day,
