SANTA CLARA, Calif. July 1, 2004-Macrovision® Corporation (Nasdaq: MVSN) today announced it has completed the acquisition of privately-held InstallShield® Software Corporation of Schaumburg, Illinois (www.installshield.com). The acquisition was originally announced on June 16, 2004.

The acquisition expands Macrovision’s product portfolio in the Software Value Management category (see www.macrovision.com/theSVMcategory) and enables Macrovision to reach InstallShield’s large software developer customer base. Macrovision expects that InstallShield’s established market leadership and strong brand equity will help to accelerate incremental sales of Macrovision’s FLEXnet™ electronic license management products. The solutions of both companies help software publishers and enterprise IT departments maximize the value of their software throughout its lifecycle from packaging and pricing through end user deployment, administration and updating. InstallShield will be integrated into Macrovision’s Software Technologies Group and Macrovision plans to continue the full-scale development and expansion of InstallShield’s existing product lines. “The combination of Macrovision and InstallShield provides our customers with complete, market-leading Software Value Management solutions for all phases of the post-development software lifecycle,” stated Bill Krepick, president and CEO of Macrovision. “This acquisition brings together two leaders in their respective markets and enables both software publishers and their customers to get the maximum value out of their software. We are very pleased at the progress we’ve achieved to-date in bringing the two companies together and getting a head start on integration.”
