ETO in Windows 10

[swpierce]

Don't use the multiCFS3 in an install other than the one you want to rename; so use the one in the ETO folder. If it already has the name you want there, just backspace once and then re enter the letter that you backspaced (or deleted), and the accept tab should work again.

I would then run the cfg.exe before trying to start the game. If there is no ETO appdata folder by then, you have a problem!
You could try moving the appdata from the old drive but I'm not sure that would work.

Have you tried copying the whole ETO from the old drive and running the multiCFS3 in that (do as I said above) after runnuing the cfg exe as well.

Yes, this is the whole ETO from my old drive.
I did the backspace and re-enter thing you suggested above.
And....
IT WORKED!
ETO up and running. All of my modded planes, facilities, effects, etc. that I thought I may have lost on the old HD.
Got some tweaking to do on the display, commands, etc. (minor stuff).

THANK YOU
