Error code: 1619 – ERROR_INSTALL_PACKAGE_OPEN_FAILED

Error description: This installation package could not be opened. Verify that the package exists and is accessible, or contact the application vendor to verify that this is a valid Windows Installer package. Resolution: In this case, the .msi is located in a subfolder in the folder. The correct reference to this file in the command line should be “subfolder\msi filename.msi”. Do not start the reference with “.\”. This can also cause the 1619 error. The complete command line should be in the form:  msiexec.exe /i “subfolder\msi filename.msi” /qn Note that quotation marks (“) are used in this example because there is a space in the file name. Quotations are not needed if there is no space in the path or file name.
