InstallShield uses EWD3 files for internal data related to its installation-development projects or processing. The exact contents and purpose of this file type are not publicly documented, so it should be treated as a private InstallShield support file.
InstallShield is Windows software from Flexera Software for creating Windows installation packages. An EWD3 file may occur alongside other files belonging to an InstallShield project or installation-development environment.
The format is not intended for independent use. Keep the file with the InstallShield project or installation that created it.
Open the associated InstallShield project or installation-development environment in InstallShield on Microsoft Windows.
An EWD3 file generally cannot be opened meaningfully as a standalone document.
EWD3 files are internal InstallShield data and do not have a practical standalone conversion process. InstallShield does not use them as a general-purpose document format.
To create a different output, open the related project in InstallShield and rebuild or export the installation package using that software. Preserve the EWD3 file with the project if InstallShield still requires it.
