The error 1619 (ERROR_INSTALL_PACKAGE_OPEN_FAILED) has an obvious cause: the MSI (or MSP) cannot be read. This problem can have different causes:
- The file is missing. Try checking if the file is present in the specified location.
- The package (MSI or MSP) cannot be read due to Security. Check security settings, make sure SYSTEM (or the user that launches MSIEXEC) has at least Read permissions.
- The file cannot be read because another process locks it for editing. Some tools, such as Orca, open MSI files in exclusive mode. To solve this, close the process that locks it (Orca, in our example) and retry the installation.
