Solved Thunderbird shows 2 profiles

[Novel8]

I have dual OS, win 7,10...but thanks to Microsoft's ending Win 7, I am forced to have Win 10, and its Free anyway. I still use mostly Win 7. I wanted to prepare myself by moving my TB setup profile on the Win 10, to my Win 10 of my laptop. I read various ways to do this, the Help/troubleshooting theory. But before attempting to do it, I reinstalled the lastest TB on my laptop, prior to do the troubleshooting aspect. To my surprise, when i went to check the installation via explorer, I noticed that it showed 2 Profile folders...so now I am confused. How can I follow through without creating a mess?

Thank you it has been resolved

Novel8, I removed my earlier comment about which profile is probably the largest because nobody seemed to reply nor care. However, I want to know what the solution was, would you mind posting what was done to fix the situation?

2 Profiles of Thunderbird

Sure, what you said made sense, but regardless, I made a copy of my win 7 TB profile on a thumb drive, used Program Manager, removed the new small existing Profile when one is created when one installs a new version of TB, entered the copy of the Win 7 Profile and all went well. Thank you.
