I am not on Windows, so I can only give you limited advice.

The LyX installer does, I believe, install LyX into \ProgramFiles. It 
should therefore be possible to install 2.5 alongside 2.4. I believe 
also that your 2.4 settings will be copied over into a new user 
directory, and the old one will be left untouched. So installing 2.4 
should not, I think, affect anything with 2.4. That said, it probably 
would be a good idea to back up your 2.4 user directory before 
installing 2.5. You can find out where it is by looking at Help> About LyX.

Your 2.4 files should continue to work just fine in 2.5. If they do not, 
then that is a bug on our end.
