QuickTime™ for Windows and DeltaGraph 

Following the discovery of two security issues in QuickTime for Windows, Apple Computer, Inc., the maker of QuickTime, announced that it would no longer provide updates for the product and was deprecating it. Many IT administrators, properly citing security concerns, removed QuickTime from corporate computers and disallowed installtion on new systems.

Red Rock Software immediately began to rewrite the parts of DeltaGraph that depended on QuickTime support. This process is complete and a new version of DeltaGraph is now available.

The changes to remove support for QuickTime have been implemented in DeltaGraph 7 only. If you already have DeltaGraph 7, please visit our Downloads page to begin the upgrade process. This is a free upgrade for current DeltaGraph 7 users.

Users of DeltaGraph 6 and older versions will need to upgrade to DG7 if they wish to use DeltaGraph on a system which does not have QuickTime installed. Please visit our store to purchase an upgrade to DeltaGraph 7.5.

“Maybe there is even an easier way to accomplish the same thing-but needless to say, I am just smiling from ear to ear about how easy it was to get exactly what I needed [using DeltaGraph].” - Frank W. Baumann, P.Eng. , Baumann Engineering
