Windows MSI Error 1619 — Installation Package Could Not Be Opened

MSI error 1619 means Windows Installer cannot open the MSI package file, typically because the file is missing, corrupted, inaccessible, or on a disconnected network share. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Error 1619 specifically means the MSI package file cannot be accessed or opened. The file path in the install command may be wrong, contain spaces without quotes, or point to a network location. Corrupted download of the MSI file is a common cause. Network share disconnection during installation triggers this error. Windows Installer validates the MSI package header before starting. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: MSI file path is incorrect or the file does not exist. MSI file downloaded incompletely or corrupted during transfer. Network share disconnected or inaccessible during installation. File path contains spaces but is not quoted in the command. Insufficient permissions to read the MSI file. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Verify the MSI file exists at the specified path and is not zero bytes. Re-download the MSI installer from the official source. Copy the MSI file to a local drive (C:\Temp\) and install from there. Use quotes around the path: msiexec /i "C:\Path With Spaces\file.msi". Check file permissions: right-click MSI > Properties > Security > ensure your user has Read access. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
