Macrovision's InstallShield X Achieves Broad Market Acceptance; Cisco, Websense Reaping Benefits of InstallShield Cross-Platform Installation Solution.

SANTA CLARA, Calif. -- Macrovision(R) Corporation (Nasdaq:MVSN) today announced that the newest release of its flagship installation authoring solution, InstallShield(R) X, is receiving high marks from users and is gaining widespread adoption. Customers such as Cisco Systems and Websense, Inc. are praising InstallShield X for greatly improving the multi-platform software installation process.

InstallShield X, released in May, is the first solution to enable software developers to author industry-standard installations targeting virtually any platform, operating system and device. As the successor to both InstallShield DevStudio and InstallShield MultiPlatform, InstallShield X is the most comprehensive and robust installation-authoring product on the market today. With InstallShield X, customers dramatically cut development time and support costs while improving communications with their end-users.

Customer Success

Cisco Systems (Nasdaq:CSCO), the worldwide leader in networking for the Internet, chose InstallShield X to meet the increasing need to install its solutions on multiple platforms in a standardized manner giving customers a consistent look and feel.

"InstallShield X reduces our development costs by supporting all of our target platforms, and decreases the time we spend on native installation methods," said John Patton, Software Engineer at Cisco Systems. "Having scaled to meet our installation needs, it allows us to integrate multiple projects into one solution creating a single setup that anyone on our team can use. Because the first thing our customers see when using our product is the installation, it's important for us to have a solution that gives our customers confidence throughout the install and uninstall processes."

Websense, Inc. (Nasdaq:WBSN), the leading provider of employee Internet management (EIM) solutions, chose InstallShield X for its ability to deliver fast installation development for multiple platforms.

"Using InstallShield X the benefits became obvious," said Willhelm Lehman, Software Installation Architect at Websense, Inc. "Our development process is now streamlined to a single code base for all platforms. This saved us money by allowing us to hire Java developers who focused on installation development on a common platform instead of concentrating on arcane UNIX shell scripting semantics. In turn, our UNIX customers were very impressed because our installation process was finally able to resemble the Windows installation."

"Developers today want to be able to distribute their applications to as many platforms as possible with one tool. For example, Linux developers want to write one setup which will deploy to all Linux distributions. Rather than make them use multiple products with dissimilar IDEs and features, we simplified the experience," said Bob Corrigan, InstallShield Product Manager at Macrovision. "We are thrilled to see customers like Cisco and Websense reaping the benefits of InstallShield X."

Software installation is a key component of Macrovision's software value management solutions, which include software updating, packaging and licensing, entitlement management, end user management, and usage optimization.
