Microsoft Visual Studio .NET

SCHAUMBURG, Ill., November 20, 2002 - InstallShield® Software Corporation, the acknowledged leader in software installation, packaging, and deployment solutions, today announced the immediate availability of InstallShield® Express(tm) 4, the newest version of its industry-leading solution for quickly and easily creating installations for Windows software applications.

Software developers are under pressure to create cost-effective installations rapidly. Express(tm) 4 offers easy-to-use solutions for common installation needs, allowing developers to build straightforward installations in less than a day. New features include revolutionary patch and upgrading technology, integration with Microsoft Visual Studio .NET, Web services support, and many other enhancements that help developers increase productivity when creating installations.

"We are committed to providing ISVs with the tools they need to quickly and easily create Windows installations," said Viresh Bhatia, CEO of InstallShield. "Express 4 incorporates over 12 years of installation experience to create the easiest and fastest path to straightforward installations."

Quick and Easy Patching Innovative new technology makes application patching and upgrading easy by allowing developers to quickly create reliable patches. Developers simply point to an existing software package, identify the file and registry changes to be made, and deploy the patch. Validation for all patch and upgrade solutions occurs automatically.

"I am really impressed with InstallShield Express 4," said John Luckett of Vesperia.net. "I have been anticipating the new features and InstallShield has shown a true commitment to software developers by adding QuickPatch and other productivity enhancements to Express. I am looking forward to creating projects with this new release."

Single Interface for All Development Express 4 simplifies installation authoring for Microsoft .NET applications through complete integration with the Visual Studio .NET IDE. Developers can now run Express completely inside the Visual Studio .NET shell or use the traditional Express IDE. Within Visual Studio, all navigation is integrated with the solution Explorer tree and each view is presented in a separate window in the workspace. The product also includes enhanced Web services support with a new IIS view that allows developers to create and configure virtual directories.

"InstallShield has a long tradition of anticipating and delivering on developers' needs," said Ari Bixhorn, lead product manager for Visual Studio .NET, Developer Platform and Evangelism Division, Microsoft Corp. "Express 4's integration with Visual Studio .NET reduces the complexity of creating .NET installations, increasing developer productivity and proving once again that InstallShield is clearly in tune with next-generation installation development trends."

Simplified Conditional Installations With Express 4, developers can use a wizard to quickly design searches for existing applications, operating systems and files. The results of the search can be used to conditionally install parts of the application or to conditionally run custom actions.
