I wanted write a comment, but my reputation score is low. Is it other build-in application in French?
Open the Control Panel
-> Clock, Language, and Region
-> Language
And check Windows display language
.
In you case should be so:
- English
Windows display language:
Available - French
Windows display language:
Enabled
Then open Change data, time or number formats
and change language in Location
tap. And finally, try change language in Language in non-Unicode programs
on Administrative
tab.
Maybe, this tutorial help you.
