About Application Isolation Wizard
Application isolation is one solution to component versioning conflicts, commonly known as "DLL Hell." Isolation
reduces versioning conflicts by modifying an application so it always loads the versions of components—such as
DLLs—with which it was originally developed and tested. This is accomplished by providing DLLs and other
shared components for specific applications, and placing information traditionally stored in the registry into other
files that specify the locations of these isolated components. Application isolation provides increased stability and
reliability for applications because they are unaffected by changes caused by installation and ongoing
maintenance of other applications on the system.
Depending on the isolation method used in the Application Isolation Wizard, you can partially or totally isolate an
application. When using assemblies and manifests to isolate applications for Windows XP systems, the assemblies
can be updated following deployment without necessitating application reinstallation.
Reasons to Isolate Applications
You would want to isolate an application if:
• You want to resolve incompatibilities between different versions of shared components.
•
You want to reduce the complexity of the installation by storing COM activation data in a manifest instead of
the registry.
•
You want to insulate the application from changes to shared components.
Tip • Following isolation, you can use the Dynamic Dependency Scanner in InstallShield Editor to verify isolated
files are loaded from a different directory.
