Is the DBsign Web Signer 3.0 compatible with Windows Vista and Windows 7?

Yes. DBsign Web Signer version 3.0 works on Windows Vista and WIndows 7 (earlier versions do not). You can download it HERE. We have seen a few issues in the past with the way that Windows handles a user's certificates in Internet Explorer's protected mode. It may be necessary to add web sites using DBsign to IE's trusted sites list. If you are still having problems, please contact our support team.
