How Can I Determine the Installed Version of Microsoft Office?

Finding Your Microsoft Office Version: A Comprehensive Guide

Knowing your Microsoft Office version is crucial for ensuring compatibility and proper functionality. This guide outlines several methods to determine your installed Office version.

Method 1: Checking the Registry

One way to identify your Office version involves examining specific registry keys. For example, to check for Word 2007, look for this key:

<code>HKLM\Software\Microsoft\Office.0\Word\InstallRoot::Path</code>

The numerical value (12.0 in this example) indicates the Office version:

Method 2: Querying the MSI Database

Alternatively, use the MSIEnumProducts API to query the MSI database. This approach is independent of registry keys.

Method 3: Identifying the Excel Version

To pinpoint your Excel version, follow the same registry key method, substituting "Excel" for "Word" in the key path. You can also use the Application.Version property within Excel itself.

Important Note: Microsoft doesn't officially support having multiple Office versions installed simultaneously. This can cause conflicts and unexpected issues.

Method 4: Office 2019/Office 365 Considerations

Office 2019 and Office 365 utilize a different installation method than previous versions, making version number tracking less straightforward. While examining the file version of "WINWORD.EXE" might offer some clues, it's not entirely reliable due to frequent updates. Distinguishing between Office 2016 and Office 2019/365 can be challenging due to this.
