Frequently Asked Questions
Why does Microsoft Project say my language is not supported?
This typically occurs if the language ID specified in your Office Deployment Tool is incorrect, or if lingering registry keys from a previous Office installation in a different language are causing software conflicts.
Can I install Microsoft Project in a different language than my Windows OS?
Yes. You can select a different language during the installation from your Microsoft Account portal by choosing 'Other options' before downloading, provided that specific language is supported by the software.
Does repairing Office fix the language unsupported error?
If the error is caused by minor corrupted installation files, running an Online Repair from the Windows Control Panel can sometimes resolve the underlying issue. However, a complete uninstall and reinstall is usually required for language mismatch errors.
Where can I find the official Microsoft Office Uninstall Support Tool?
The official Microsoft Support and Recovery Assistant (SaRA) tool can be downloaded directly from the Microsoft Support website under the 'Uninstall Office from a PC' help section.
