License Query

Hi admin,

I just want to make clear regarding the license available for download of Dolphin 6.1 on the download page. My concern is which one to properly download and install to avoid installing it twice, are both Dolphin just the same source codes? I really don't mind the adds on the Ray and Orca. My concern is the advertisements. As says below:

1) Dolphin 6.1 + Free Ray 3.5 + Orca 2.0 (10 Mb)

2) Dolphin 6.1 + Ad-Free Ray 3.5 + Orca 2.0 (10 Mb)

I just downloaded the first one. I already installed this on my site but my concern is the advertisements. The advertisements on the Ray and Orca is no problem but the main page in dolphin bottom page.

If I buy the license considering I already installed the free. Do I need to re-download the second (Ad-Free) item and re-install again from scratch?

Is the Dolphin both has add? Is the Dolphin on the two items same source codes? And only addvertisment code differences?

What happens if I already have free dolphin installed and working then purchased the license for Dolphin, how and can I remove the adds?

If the the two items above can be explained in detail with regards to license will be much better so I can move in with my new site. Thanks
