New Downloaders for English and German

We became aware of an issue affecting the previously available German and EU English versions of the digital install downloader for Diablo III, which would not download all the necessary files. If you've pre-downloaded the digital version of the game in these languages before 10:00 AM CEST (9:00 AM GMT) on Saturday May 12, you must obtain the new downloaders to be able to install properly once the game is released on May 15. We apologize for the inconvenience, and ask that you please let friends and acquaintances know so they can begin downloading the working installer that's now available.

1. Obtain the new Diablo III digital downloader using the links below
2. Point the download save at the same directory as before

The folder in question is your main game data folder. If you have the game downloaded to D:\Games\Diablo-III-8370-enGB-Installer, please point the download to D:\Games\. Do not use the automatically generated folder containing the installation files (i.e. do not use the directory D:\Games\Diablo-III-8370-enGB-Installer as this is the one created by the downloader). 
3. If you chose the correct directory only around 65MB will need to be downloaded to fix your install, otherwise you'll re-download the entire ~7.6GB

New EU English Installer
New EU English Installer (Mac)
New German Installer
New German Installer (Mac)

For more information or help with the installation, check out the Diablo III Pre-Sale Downloader Walkthrough or use the search on the Battle.net support site.

Whether you repair your previous install or download the entire game again, it's necessary to use this new downloader to install and play the game when it launches.

@Pustule: Make sure you're pointing it to the same place you did before, and not the folder the download created.

@Alexíz: That error should only appear if you're attempting to use the old downloader. Grab the new one from the links above.

@Maldivia: This is correct. If you want to play the game right at European launch we would recommend you download with the updated European downloader.

@redeemer: No, from now on everything should be just fine. Just this once. :(

Sorry about the extra worries on this. I hope everyone manages to see this this weekend so they don't have to figure it out on Monday. Please do tell your friends about this as much as you can and share the Facebook update about it.

@SyngeN: Once the game is live in all regions that will be possible. But you'll have to wait until midnight US time for Global Play to be activated. You can do this with the EU version as well with the additional benefit of being able to play in the European region 9 hours earlier. ;)

@PaCaTa: Yes, you won't have any issues with installation from DVD. This affects the digital downloaders only.
