How do I create setup with Auto Updater

[testuser]

Hello,

I am checking WUPDATE_SSL.EXE and for testing I have kept ini file at dropbox now I am getting "Cannot download server manifest file.Network Communication Error: 509000004", even I have tried #pragma HTTP_DISABLE_SNI = "1" in product and WUPDATE_SSL.sbp as well.

below is the ini file

LOCAL_CHECK=1
LOCAL_LAST=0
HOST_ADDRESS=www.dropbox.com
HOST_PORT=80
