Fine here in the UK

There where some issues with the download servers it should be fixed by now if you can confirm.
Thank you!

UPDATE: for those that cannot download, make sure you don’t have the hosts file additions such as:

These were used for online Comodo CIS setups.

Update 2: It looks like the Beta was updated slightly and the posted checksums are no longer valid. We are now at v80.0.3987.87.

Can’t download from US. 404 Not Found. The one on the page seems to be 32 bit only.

Hello At the moment we are on version v80.0.3987.163, this is the beta version v80.0.3987.66 and we did another release for beta v80.0.3987.87…of course the beta links wont download v80.66…can you download the latest versions.80.163?

Thank you. I was able to install Version 80.0.3987.163 to test.

With pleasure, hope you enjoy our latest build, don’t forget to leave us a feedback about it

Working pretty well so far. But I noticed the Comodo Media Downloader is missing. Is this still available somewhere?

Hello, unfortunately due to latest video updates (youtube, dailymotion, vimeo,etc) Media Downloader doesn’t work anymore we are stil working on it.
