FF6LE & SNEStuff expanding

I had install .NET Framework to try to open the sln file, but it said it need to be migration. Am I doing this right?

You would be doing this if you want to modify the source code, otherwise just use the exe available here:

If you are talking about FF3LE sln file as the exe, well I can't opened it, bec well...its a sln file. If you are not talking about that, then I have see no exe inside FF3LE folder.
