Method 4: Restore from the Hidden MSI Cache (Advanced)

Windows stores copies of MSI files in the C:\Windows\Installer folder. However, file names are obfuscated (e.g., 572a31.msi). You can find the correct file via Windows PowerShell:

  1. Open PowerShell as Administrator.
  2. Run this command: Get-WmiObject Win32_Product | Where-Object $0.Name -like “*Office*” | Select-Object Name, LocalPackage
  3. Look for your Office product. The LocalPackage column will show the full path to the cached MSI file (e.g., C:\Windows\Installer\572a31.msi).
  4. Copy that file to your desktop and rename a copy to Officemui.msi.
  5. When the installer asks for the file again, browse to this copy.

Method 3: Perform a Complete Uninstall and Reinstall (Most Reliable)

If the file is permanently missing, your MSI cache is corrupted. The only safe way to get a clean Officemui.msi is to remove Office completely and reinstall from a legitimate source. Office Language Packs Office Proofing Tools Office Shared

Step-by-step:

  1. Download the Microsoft Support and Recovery Assistant (SaRA). This is Microsoft’s official diagnostic tool.
  2. Run SaRA and select "I can't install Office" > "Advanced" > "Office 2013/2016".
  3. SaRA will completely scrub every version of Office, including all MSI files and registry entries.
  4. Reboot your PC.
  5. Reinstall Office using one of these legitimate sources:
    • Office 2016/2019/2021: Log into setup.office.com and click "Install."
    • Office 2010/2013: Download the official ISO from the Microsoft Volume Licensing Service Center (VLSC) if you have a license. For retail versions, use your original installation disc or download from your Microsoft Account under "Services & Subscriptions."

After reinstallation, the correct Officemui.msi will be safely stored in the MSI cache folder (C:\Windows\Installer).

Method 2: Use the Microsoft Office Deployment Tool (ODT)

The Office Deployment Tool (ODT) is a free tool provided by Microsoft that allows you to customize and deploy Office installations. You can use ODT to download Officemui.msi as part of the Office installation process.

  1. Download the Office Deployment Tool.
  2. Extract the tool and create a configuration file (e.g., config.xml) that specifies the Office installation settings, including the language and architecture (32-bit or 64-bit).
  3. Run the ODT tool with the configuration file to download and install Office, including Officemui.msi.

Why You Should Never Use Third-Party Sites:

  1. Malware Injection: Cybercriminals embed trojans, ransomware, or keyloggers into seemingly legitimate MSI files. Since MSI files run with administrative privileges, they can fully compromise your system.
  2. Version Mismatch: Office 2010, 2013, and 2016 use different versions of Officemui.msi. Using the wrong version will corrupt your Office installation entirely, leading to error codes like "Error 1706. No valid source could be found for product Office."
  3. Missing Digital Signatures: Genuine Microsoft MSI files are digitally signed by Microsoft. Third-party downloads lack this signature, or the signature is forged.
  4. No Future Updates: Even if a downloaded file works temporarily, it will break again the next time Windows Update runs because the cached file path is incorrect.

Rule of thumb: Never download Officemui.msi as a standalone file from the internet.
