Virtual (what?) when using Sage 4.7 for Windows

edit

Update: It's been a week since I asked how to install the program. What am I supposed to do? I need help or I can't use the program. What is up?

Update 2: I installed Virtual Box and tried installing the file and that didn't work either! I had downloaded the 4.7 Update 1 file. Now, it doesn't exist on the website. Thus, the problem may have been with the "sage-4.7-update1" file. I finally redownloaded the file (and noticed afterward that it was different) and this new file may work just fine now. It works fine now. Thanks.

This question has been changed quite a bit. It's the same question but I have more info now so I say what I'm trying to ask better:

In the past, people had problems installing Sage for Windows using the Virtual Box because the instructions were out of date. In fact, the main instructions told you to use Virtual Box but didn't work. So, this caused many people headaches, more so than if they instructions had just said "Don't use Virtual Box, these instructions are out of date. Instead, use the VMWare instructions." They were out of date for somewhere around a year, or more, based on the comment (below link) from October 2010 suggesting the instructions be updated, and the fact that the instructions were just updated in the last few weeks, for Virtual Box. In fact, another comment on this same question say that there was no support for Virtual Box for quite a while.

Now, the file was changed to an ova and the instructions only mention how to install it for Virtual Box. There is no mention at all about VMWare Player. If you click to download the file, you can get the VMWare Player instructions, but they are out of date, i.e., they are for the previous file type. Since the instructions only mention Virtual Box, are you telling me I now need to install Virtual Box, or are the VMWare Player instructions coming soon? I have tried installing it and I have no idea how to get it to work.

Lastly, is there some sort of general idea for when the native Windows version will be ready?

Thanks for any help
