Question

MS Project does not switch the languange after changing the setting in Options

Zbyněk Hovorka 0

Hello,

For some reason the display language of MS Project cannot be changed from Czech to English. I am using Office 365 for business. I have changed the following language settings: Office user interface language (set as preffered) and languages for creating content and grammar check is set to English - see attached printscreen. The display language for Word & Excel is displaying correctly in English after the change. MS Windows language is Czech - ("The same like in MS Office") in the options but not selected.

Please support me.

Thanks!

Thank you for your fast response.

I am a regular user, not installing the software and not fully aware about which Office version is installed - I see only MS Copilot 365 in the applications list, being installed since I received the laptop, having Czech language are the primary one in the setup.

The same problem appeared already in the formu but probably not solved: https://learn.microsoft.com/en-us/answers/questions/5060108/incorrect-display-language-ms-project?source=docs

Hello @Zbyněk Hovorka,

Thank you for your responding.

I did come across the Q&A thread you mentioned while researching your case. However, since the proposed solutions in that thread have not been confirmed as working by the original poster, I chose not to include them in my earlier response.

Additionally, I noticed that you mentioned having received a laptop. Could you please confirm whether this laptop was provided by your company?

If this is a work account, you can sign in to Harmony Portal: My account to check whether your subscription is assigned. Could you share a screenshot of that page?

Thank you for your understanding!

Hello @Zbyněk Hovorka,

Thank you for waiting.

Regarding the second screenshot from Project => Options => Language, although you have already set English as the preferred language under Office authoring and proofing, I still cannot clearly see the status of the English language pack. Normally, this section should show one of the following statuses: Proofing installed, Proofing available, ...

If the language pack is not actually installed, Project will not switch to English even if English is set as the preferred language.

So, could you please double‑check whether the English language pack is fully installed?

If not, you may consider downloading and installing it from the official Microsoft link below (make sure to choose the correct bit version; 32‑bit or 64‑bit): Language Accessory Pack for Microsoft 365 - Microsoft Support

If the language pack is already installed correctly, but Project still displays the wrong language; especially if this is a company‑managed device; I strongly recommend that you contact your IT administrator and ask them to verify this on your device. They may also reinstall Project for you using the correct subscription-based installer.

If the issue still persists after that, your IT admin can also help you raise a support ticket with Microsoft for further investigation.

To create a Support ticket, they can go to: Microsoft 365 admin center

When they click Help & Support in the bottom-left corner, a Support Assistance panel will appear.

In the text box, they can type: "request an agent to contact me via email or phone" and press Enter.

After that, please look at the bottom-left corner of the panel. They will see a blue link that says, "Contact Support"; they click on it.



They will then have two options: Support via phone or via email. They can choose Email.

Fill all the information in this contact support details. Please describe your situation carefully so they will have enough information to help you.

Finally, clicking on "Contact me"

Please follow this article: Get support - Microsoft 365 admin | Microsoft Learn

After completing them, you will receive an email appointment for a meeting to review this issue professionally together.

I apologize for redirecting you to the support team. As forum moderators, I have limited access to backend systems and cannot directly investigate device-level issues.

I truly hope you’ll be assisted soon by our dedicated technical team. And if you receive any updates or insights, please feel free to reply here.

Looking forward to hearing from you

Hello, I attach the full printscreen of the settings - seems English (Angličtina) is installed for the Proofing (Kontrola pravopisu - spell and grammar check) Language setting MS Project.png

I will turn on our IT support, maybe reinstallation would help. Or later we can use official support.

Thank you.

Hello @Zbyněk Hovorka,

Thank you for responding.

As your screenshot you provided, the language pack has been installed correctly. If you receive any updates from your IT admin or from Technical Support after raising a ticket, please share them here.

Answer 2

Hello @Zbyněk Hovorka,

Thank you for reaching out to the Q&A forum!

Before providing more specific guidance, I would like to clarify a few points to better understand your scenario:

I noticed that you mentioned an attachment in your description; however, I’m not able to see any attached files at the moment. Could you please share the attachment again so I can review it more accurately?
Could you please clarify how Microsoft Project was installed on your device?
Additionally, could you please let me know whether you are a regular user or a Microsoft 365 administrator?

When I test in my environment, after going Options => Language I set Office display language and Office authoring languages and proofing to English.
User's image

Microsoft Project was able to switch its entire interface to English successfully.

So, I will wait for the screenshots from you so that I can review the setup and continue researching the issue.

Please understand that our initial response may not always resolve the issue immediately. However, with your help and more detailed information, we can work together to identify the root cause and find a solution.

Looking forward to hearing from you!

It seems you are experiencing an issue with changing the display language in MS Project while it works correctly in Word and Excel. Here are a few steps you can try to resolve this issue:

Check Language Settings: Ensure that the preferred language for the user interface is set correctly in MS Project. Sometimes, settings may not apply uniformly across all Office applications.
Office Deployment Tool: If you are using the Office Deployment Tool, ensure that the configuration file specifies the desired language correctly. The first language in the configuration file determines the Shell UI culture.
Reinstall MS Project: If the language settings are not applying, consider uninstalling and then reinstalling MS Project to see if that resolves the issue. This can sometimes reset the language settings.
Windows Language Settings: Even though you mentioned that Windows language is set to Czech, ensure that the display language in Windows is set to English if you want MS Project to reflect that change.
Updates: Make sure that your Office 365 installation is up to date, as updates can sometimes fix bugs related to language settings.

If these steps do not resolve the issue, you may need to consult Microsoft support for further assistance.
