I'm sorry that you're experiencing problems with downloading our app.
Are you getting this error within your browser while trying to download the installer or were you able to download the installer and am getting this error from within the installer?
Have you tried using another browser like Chrome or Firefox?
What happens when you try to download? Does it immediately fail or does it get to 99% before failing?
Are you using any download scanners on your PC? We've had some reports that download scanners are flagging our installer because of the OpenCandy component.
This detection is erroneous or a "false positive" as OpenCandy is not adware. OpenCandy is partners with some of the largest anti-virus and anti-malware companies. Here is their statement on these false positives.http://www.opencandy.com/learn-more-about-opencandy-and-false-adware-detections/
We are working with OpenCandy and the major anti-virus companies to remove any false positive detections from their databases. In the meanwhile, please temporarily disable your anti-virus software to download/run the doubleTwist installer.
To disable installation of any OpenCandy suggested applications, please carefully review the choices available and choose the appropriate option so that it does not install. You do not need to install any of the OpenCandy suggested applications in order to install the doubleTwist application.http://www.doubletwist.com/help/question/how-do-i-opt-out-of-installing-the-opencandy-suggested-application/
