ERROR_INSTALL_PACKAGE_OPEN_FAILED
ERROR_INSTALL_PACKAGE_OPEN_FAILED means that Windows Installer could not open the requested package. The cause can be a missing source, inaccessible location, or a file that is not usable as the intended MSI package.
What to check
- Verify the exact path, file availability, and read access in the security context that starts the installer.
- For a deployment share or downloaded package, confirm the content was fully obtained before launching it.
- Keep the package version and its source URL or distribution path in the installer log for repeatable diagnosis.
