Question details

The user is trying to install Italian proofing tools in Microsoft 365 but is confused because the system repeatedly downloads a generic OfficeSetup.exe file that looks like a full reinstall.

Product
Microsoft 365
Device & OS
not provided
Scenario
Adding a new language accessory pack or proofing tools to an existing Microsoft 365 installation.
Observed behavior
Selecting the Italian language pack downloads a 7.2 MB OfficeSetup.exe file that appears to perform a full Office reinstall instead of just adding the requested language features.
Before you start

Ensure you have a stable internet connection and close any open Microsoft Office applications before running the language pack setup file.

Solution 1Recommended

Run the OfficeSetup.exe File to Install the Language Pack

Proceed with the generic OfficeSetup.exe installer, as this is the standard Microsoft 365 behavior for adding new language accessory packs.

When you download a language accessory pack, Microsoft 365 provides a generic 7.2 MB OfficeSetup.exe file. Although it displays the standard Office installation screen, it is actually just installing the selected proofing tools and sharing existing Office resources.

1
Locate the installer

Find the downloaded 7.2 MB OfficeSetup.exe file in your computer's Downloads folder.

2
Run the setup process

Double-click the file to launch the Microsoft 365 installer and allow the setup process to complete. It will run significantly faster than the initial Office installation.

Multiple Product Entries: You may see a second Office product entry in your installed programs list. This is normal when a language accessory pack is added to an existing installation.
Free Microsoft Office alternative

Try WPS Office for a Hassle-Free Multilingual Experience

If Microsoft 365's installation processes and generic setups are causing confusion, consider switching to WPS Office. It is a free, lightweight, and highly compatible Office suite that makes managing multiple languages and proofing tools incredibly simple without confusing setup screens.

  1. 1. Install WPS Office: Download and install WPS Office from the official website.
  2. 2. Access spell check settings: Open WPS Writer and navigate to the 'Review' tab on the top ribbon.
  3. 3. Set proofing language: Click 'Spell Check' and select 'Set Language' to easily download and apply Italian or other proofing tools.
Easily switch spell check and proofing languages directly within the app.Fully compatible with Microsoft Office file formats (.docx, .xlsx, .pptx).Lightweight installation that takes up significantly less disk space.Familiar user interface for a seamless migration from Microsoft 365.

Frequently Asked Questions

Why does the Microsoft 365 language pack download OfficeSetup.exe?

Microsoft uses a unified Click-to-Run installer. The 7.2 MB OfficeSetup.exe file is a small stub that downloads only the necessary components for your selected language, even though it displays the standard Office installation screen.

Will installing a language pack reinstall my entire Office suite?

No, it will not reinstall the entire suite. The installer shares existing resources and only adds the requested proofing tools, making the process much faster than a full suite installation.

How do I change the default proofing language after installing the pack?

Open an Office app like Word, go to File > Options > Language. Under the 'Office authoring languages and proofing' section, select your newly installed language and click 'Set as Preferred'.

Why do I see two Microsoft 365 entries in my installed apps list?

Installing a language accessory pack often creates a separate entry in the Windows installed programs list for the specific language, alongside your main Microsoft 365 installation. This is expected behavior and does not mean the software was duplicated.
