Please note: The new ProofHQ Viewer requires version 11.1 of the Adobe Flash Player. For the Mac systems - this version of the Flash Player can only be installed on Mac OS X 10.6 and higher. For the older Mac system versions Flash Player 10.3 is the highest available version.
If your are working inside a network with higher security levels it may be required for your Administrators to whitelist ProofHQ connections. We would recommend to whitelist:
- 188.8.131.52 for ProofHQ account access
- 184.108.40.206 for www.proofhq.com website and blog access
- s3-us-west-2.amazonaws.com and cdn.proofhq.com - for opening the proofs (once the proofs are processed we load the contents to the cloud)
- 220.127.116.11 (webcapture.int.proofhq.com) - for proofing the authorised web pages or pages behind firewall
We realize that, in some cases, there is not only a desire but a necessity to run Flash Player on an unsupported machine. Flash Player 10 is not available for Microsoft Windows 98, Microsoft Windows ME, Macintosh OSX 10.1 – 10.3, and Red Hat® Enterprise Linux 3 and 4 operating systems. In this situation, we recommend installing the latest Flash Player available for your operating system to take advantage of the most recent security and stability updates to Flash Player 9.
Please note: Our new ProofHQ Viewer requires at least Flash Player 11.1.x
Adobe recommends that all Flash Player users on supported systems update to the most recent version of the player through the Flash Player Download Center.
