Draftsight 2016 installation folder location option?

Hi,

Please can you tell me if there is a option to change the destination folder during installation of the free version of Draftsight 2016?

I am currently using version R4 and thought it was time to upgrade to version 2016. However after installation I had found that it had uninstalled R4 from my chosen folder and installed 2016 somewhere else. The R4 desktop icon was still there, but when I clicked it 2016 loaded instead and thus I had lost all my settings for R4. The only way to get back R4 with all its settings was to run a system restore point.

I want to change the destination folder so that I can review both versions side by side rather than remove the older version. I prefer to keep track of the software I use in a particular installation folder rather than the default folders.

Thank you
