Make sure you get an account at the store. The software is pretty useless without an account. It'll also take an hour or so to DL the real program and all the art.
MTGnews has a good thread in the magic online forum that explains how to install the software. Here are the instructions:
1) Download the zip file from the german site.
2) Then, unzip it, using a program such as winzip. (
http://www.winzip.com)
3) Unzip the .zip file inside the downloaded zip file into a new folder without any other Non-MTGOnline files.
4) Run Setup (note: Setup will download files from the WotC server. The last 10 percent of the download will take considerably longer because of the number of files downloaded)
5) Once they are downloaded, follow the instructions to install Magic Online
6) Once Magic Online is installed, move all of the contents of the .zip files into the magic online folder. Just the programs, not any specific folders.
7) If it prompts you to overwrite, DO NOT OVERWRITE ANY FILES.
8) Afterwards, delete the file (updated.lst)
9) Run Setup Again
10) It will update the program to the newest version (from 8.39 to 8.43)
11) Then, run "magic", "magic1", or "modo" to start MTGOnline. (note: magic and modo check for updates before running. magic1 does not.)
12) Now that Magic Online requires version .845, you will need to do an additional step. Open the "modo" file in the MTGOnline Folder where you have all of your programs. That will run the update program and it will download the necessary files.
The version is much higher than .843 now.

mods - ps - this is beta software and WotC has been allowing the downloads. they control the beta via releasing accounts and will be making the software free for download once it is completed. This isn't "warez". You'll have to pay per pack once the game goes out of beta.
