MACROVISION ACQUIRES ZERO G SOFTWARE, INC.

Extends Macrovision's Leadership in Maximizing the Value of Software on Any
Platform

SANTA CLARA, Calif. - June 13, 2005 - Macrovision Corporation (Nasdaq:
MVSN), the leader in Software Value Management, today announced that it has
acquired privately-held Zero G Software, Inc. of San Francisco, Calif. Zero
G is a leading provider of software deployment and delivery solutions for
multi-platform operating system environments. Financial terms of the
agreement were not disclosed, but Macrovision stated that the transaction
would be EPS neutral in 2005, and accretive in 2006.

"The combined expertise of Zero G and Macrovision will provide software
publishers and their customers with a seamless software installation
experience across all platforms," stated Dan Stickel, EVP/GM, Software
Technologies Group, Macrovision. "This acquisition further increases the
market for our Software Value Management solutions, adds innovative
technology and people to the company and enhances our multi-platform
products."

"Software is facing a complexity crisis. With this agreement, two leaders
in installation and software deployment have joined forces to simplify the
installation of software in complex multi-platform, multi-server
environments," stated Eric N. Shapiro, CEO of Zero G. "Zero G's
enterprise-focused multi-platform installation products will complement and
enhance Macrovision's industry-leading InstallShield solutions, which are
the de facto standard for Windows installations. In addition, Zero G
customers will benefit from Macrovision's broad Software Value Management
platform that enables publishers to flexibly price, package, license,
protect and update their software applications."

Software installations are a critical factor in the overall value of
software derived by customers. According to IBM Autonomic Computing
research, 28% of all application failures are related to installation and
configuration errors. The combination of Zero G and Macrovision
technologies will benefit customers by simplifying the installation and
management of enterprise software, offering the industry's premier
installation experience on every platform. Both Macrovision and Zero G have
been at the forefront of solutions for complex software installation and
have worked closely with key standards bodies and industry partners
including OASIS, WC3, IBM, HP and others to establish standards in the
industry such as the Solution Deployment Descriptor Specification (SDD),
also known as "Solution Installation."

"Enterprises are continually seeking new ways to reduce the total cost of
managing, updating and installing software. Streamlining these processes
starts with simplifying the management of large, interdependent software
solutions running in increasingly complex IT environments," stated Audrey
Rasmussen, vice president, Enterprise Management Associates. "By bringing
Zero G into the fold, Macrovision can quickly deliver more value to both
ISVs and their enterprise customers by automating time-consuming and
error-prone manual software management processes."

Zero G Software will become part of Macrovision's Software Technologies
Group and expand Macrovision's product portfolio in the Software Value
Management category. Macrovision will continue to provide support for all
Zero G products. For more information on the strategic rationale for the
acquisition and a list of FAQs, please visit the Macrovision website at
