Minelab Xchange2 functions perfectly OK for me in Windows 10.
I cleared, by deleting, all other folders out of the red column of Xchange2, that I thought were unnecessary.
The three remaining ones can not be deleted, so they remain.
After you have downloaded one or any other of the *.mlf files to a directory on your computer, plugged your CTX3030 in and started Xchange2, you should see and hear the CTX3030 plugged in and you should be ready to go.
I found it easier to deal with this matter by creating a new folder in the RED right had column of Xchange2. This cab be done by clicking on the + icon next to COLLECTIONS at top of red column.
I called mine MLFS. It can be called what ever you like.
Click on the icon (with blue arrow pointing at it in red column called FILE). You then need to import (blue arrow on right top pointing at import switch) any one of the MLF files of your choice that you have download and stored on you pc.
Drag and drop the relative file into the folder you created like my MLFS folder and you'll be able to edit that file completely and then drag it into you CTX3030 folder when you've completed what ever you need to adjust. You can also drag and drop files from the CTX3030 intself into this new folder and alter by editing and save them back.
If you're not aware of this , there is also some info here
