Scenario
Cleaning up redundant software installations to prevent program conflicts while ensuring spelling and grammar tools for multiple languages remain fully functional.
Observed behavior
Having both Office 2021 and Microsoft 365 installed simultaneously causes software conflicts and consumes extra storage, even though the user only needs one suite and multiple language tools.

Uninstall Microsoft 365 and Configure Office 2021 Language Settings

Safely remove the conflicting Microsoft 365 installation from your system and set up your required English and Swedish language tools directly within Office 2021.

Microsoft advises against keeping multiple versions of Office on the same computer due to file association conflicts and unnecessary storage consumption. You do not need a second full installation just to use different proofing languages.

1
Open Windows Installed Apps

Press the Windows key + I on your keyboard to open Windows Settings. Navigate to 'Apps' and then select 'Installed apps' (or 'Apps & features' on older Windows versions).

2
Locate and Uninstall Microsoft 365

Scroll through your list of installed programs to find 'Microsoft 365'. Click the three-dot menu icon next to it (or left-click the application name) and select 'Uninstall'. Follow the on-screen prompts to remove it, ensuring you do not accidentally select 'Office 2021'.

3
Access Office 2021 Language Options

Once the uninstallation is complete, open any Office 2021 application, such as Microsoft Word. Click on 'File' in the top-left corner, select 'Options' at the bottom of the sidebar, and then click on the 'Language' tab.

4
Add Required Proofing Languages

Under the 'Office authoring languages and proofing' section, check if English and Swedish are listed. If either is missing, click the 'Add a Language...' button, select the language you need, ensure the 'Get proofing tools' box is checked, and click 'Add'.

Frequently Asked Questions

Why is it bad to have both Office 2021 and Microsoft 365 installed?

Installing both versions on the same computer can cause software conflicts, such as file association errors where documents open in the wrong version, registry overlaps, and it unnecessarily consumes system storage.

Will uninstalling Microsoft 365 delete my personal documents?

No, uninstalling the Microsoft 365 software will only remove the application files. Your personal documents, spreadsheets, and presentations saved on your local hard drive or cloud storage will remain completely untouched.

How do I add Swedish proofing tools to Office 2021 without a full installation?

You can add proofing tools directly within the app. Open Word, navigate to File > Options > Language, click 'Add a Language' under Office authoring languages, select Swedish, and let Office download just the necessary grammar and spelling tools.
