Migrating from User to Service install on Windows

I personally would prefer Duplicati to use c:\ProgramData\Duplicati when running as a service instead of …systemprofile\AppData. It seems a little cleaner in my mind and more in line with what I see most applications doing, but it doesn’t really matter. I could always move it if it really bugged me

You can set the environment variable DUPLICATI_HOME=C:\ProgramData\Duplicati and it will stop using %LOCALAPPDATA%Duplicati.
