Language will not change..

I have downloaded to 3 different computers, windows and Linux, and upon install, English is presented, but every time subsequent attempts to start software have come up in French.  Have tried .90 and .100 Dev, both present same behavior, my French is not bad, fiancee is French and helps me when she is available, (the technical side is a bit tricky).  But to effectively use this I need English, or a large brain upgrade.

I have tried changing to other languages, and that still drops me back to French, so it seems to be systematic.

Is there a trick to setting the language so it sticks?

Ready for any feedback.
Thanks!
