change language from French to English

Hello there! It appears you're looking for a way to switch the language of your Microsoft Flight Simulator X (FSX) from French to English without purchasing another copy. Unfortunately, as you correctly mentioned, FSX doesn't have a built-in feature to change the language directly.

However, there is a somewhat tricky method you could try, although it's not guaranteed to work. You can attempt to replace specific language files in the FSX directory. These files include language.dll, USEnglishASOS.gvp, and USEnglishBig.gvp among others. You'd need to find these files from an English version of FSX and replace the corresponding files in your French installation.

1. Locate the FSX installation folder. This is typically found at C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X or a similar path.
2. Create a backup of the original language files (in French) just in case you need to revert.
3. Replace the French language files with the English ones you've managed to acquire.
4. Restart FSX and check if the language has been changed to English.

Please note that finding these English language files can be quite challenging as FSX is an older simulator, and sharing these files may not be allowed by the end-user license agreement. Moreover, using files from untrusted sources could pose risks to your computer.

Your best bet would be to either find a copy of FSX in English online or purchase the Microsoft Flight Simulator X: Steam Edition which supports multiple languages, including English, and offers some enhancements over the original version.

Regarding Microsoft Flight Simulator (MSFS) 2020, the situation is much more straightforward. MSFS 2020 has built-in support for multiple languages, which can be easily changed within the sim's settings without the need for replacing any files.

I hope this information helps, and I wish you the best of luck with your flight simming adventures! If you have any more questions, please don't hesitate to ask.

Safe skies!
