Macrovision's AdminStudio Product Chosen as Preferred Application Packaging Software for Citrix

Collaboration Benefits Customers by Offering a Simple Solution for Packaging and Streaming Software Applications over the Network

Santa Clara, CA - Sep 10, 2007 - Macrovision Corporation (NASDAQ: MVSN) today announced that Citrix® Systems Inc. has selected Macrovision's AdminStudio® software packaging product as a recommended tool for packaging applications for delivery via Citrix Presentation Server™ 4.5, the de facto standard for delivering Windows applications at a lower cost. The announcement is the result of a collaborative effort by both companies to make it easier for customers to use the application virtualization capabilities of Presentation Server 4.5. By using the two programs together, Citrix and Macrovision customers can benefit from the time and cost savings of being able to employ virtualization technology over their networks.

As of today, Macrovision's AdminStudio is available for purchase from Citrix Solution Advisors through distribution agreements with Alternative Technology in North America (see separate press release from Alternative Technology) and Centia and AKS in Europe. The availability of Macrovision's AdminStudio through the Citrix channels demonstrates continued growth in the relationship between the two companies, first announced in January and strengthened by the launch of AdminStudio 8.5 with application virtualization support for Citrix Presentation Server 4.5.

"The new application virtualization capability in Presentation Server 4.5 helps eliminate application conflicts and enables IT administrators to deliver and use applications even when later disconnected from the network," says David Roussain, Vice President of Product Marketing, Virtualization Systems Group, Citrix.  "Macrovision's AdminStudio will help IT Administrators package and deploy their applications with minimum effort and reduced cost, enabling them to more quickly use application virtualization for all of their applications and see immediate cost savings across all their desktops."

By using AdminStudio to quickly and easily prepare software for application streaming with Presentation Server, customers will have the ability to prevent application conflicts and to reduce testing, deployment, maintenance, and support costs. Macrovision's AdminStudio product, designated Citrix Ready™ for Citrix Presentation Server 4.5, can help IT administrators ease their workloads by automating the process of converting legacy applications to Citrix profiles and cut costs associated with preparing applications for streaming in Citrix -driven network environments.

"Organizations are seeking faster and more reliable methods to deploy traditional or 'virtual' software throughout their workforce," said Mark Bishof, executive vice president and general manager, Software Business Unit, Macrovision. "AdminStudio is a leader in software packaging for traditional deployment. Now, with our support for the application virtualization capabilities in Citrix Presentation Server, we can support virtual environments. The results are that IT administrators can package once and get multiple formats, speeding the packaging process, and therefore reducing costs, all while making applications more reliable and easier to deliver."

More information about the relationship and an evaluation version of AdminStudio are available at CitrixReady.com or Macrovision.com.
