Please update your links/bookmarks

(Edit: Though the beta is closed I'm leaving this up because this can come up also sometimes if you install Lotro on the same computer on Vista and also there are a few other causes of this as well on Vista/XP also)

Sometimes on Vista after installing Lotro (and in some other instances), the DDO launcher hangs at "Examine Programs." To fix this, please go into the folder you have DDO installed (Typically C:\Program Files\Turbine\Dungeons & Dragons Online – Stormreach) and run this file (if this is happening on XP look for the steps in parenthesis):


Right-click and choose “Run as Administrator” to run the file and the DDO Live server client should launch correctly.
(On XP: Double click the TurbineRegisterGDF.exe file)

If it still hangs at examine programs in some rare cases you might need to manually perform the functions of the TurbineregisterGDF.exe program:

1. Click the blue Windows logo button -> All Programs -> Accessories -> Right Click on Command Prompt
(On XP: Click on "Start" > "Run" and type "cmd" without quotes, hit "Enter" and skip to step 3)
2. Select: Run as Administrator
3. Type the following line in the Command Prompt Window:

CD “C:\Program Files\Turbine\Dungeons & Dragons Online – Stormreach”

UPDATE: Or if you reinstalled with the updated DDO:U Mod 9 installations use this:

CD "C:\Program Files\Turbine\DDO Unlimited"

(It will look roughly like this in the Command Prompt window, appearance will vary but the command should look just as detailed)
C:>CD "C:\Program Files\Turbine\Dungeons & Dragons Online - Stormreach"
C:>CD "C:\Program Files\Turbine\DDO Unlimited"
(If using Windows XP or Vista 64bit use one of these below instead):

CD “C:\Program Files (x86)\Turbine\Dungeons & Dragons Online – Stormreach”

CD "C:\Program Files (x86)\Turbine\DDO Unlimited"

4. Hit enter
5. Type: Regsvr32 PatchWrapper.dll
6. Hit enter (you should get a success message)
7. Type: Regsvr32 PatchWrapperPS.dll
8. Hit enter (you should get a success message)
9. Try launching the game again
