Can not install!

@Danycian

Did you tried to run Origin as Administrator during installation?

Yes, it made no difference.

@Danycian

Please create a DxDiag in text file format and post it with your next reply. You can do that  with the "choose file" button at the bottom right corner of the reply window. 

I assume that this is a permissions problem, did you tried to install to a different drive then before?

Same drive as before. 

Hey Holger1405 😉

Seems to be he has the same problem as I have. As you requested here is mine DXDIAG.

I don't use Windows 10. My suspiction is a problem with this "IGameExplorer2". But I can't find an application with that name in the Windows-Environment.

@MacCommando

Did you tried to install to your C drive?

Try to install the game after this guide. > test

@Danycian

Please also look at the guide I linked above and set your UAC accordantly. (just for the installation, set it back to it's original state afterwards.) > test.  

Unfortunately this made no difference. Wish we didn't have to use the Origin client, reading online all the problems people have with Origin and Mass Effect 3 in particular, it's just a shame.

Right, no difference.

@holger1405 You are right, the error 80070005 is in principle responsible for lack of permissions. But I've done everything in this direction. There are no restrictions on my system and I never have had such an error in the past.

Do you know GTA IV? This is a problematic game where some hurdles are need to take. And it runs perfectly on my System. And, it is also a "Windows Game Explorer" Game. Or NFS III - also no problem - and for this you have to be an PC-Expert ;-).

Why could M3 not use Steam like part 1 and 2? This runs also perfectly on my system.

I tried just for fun to reinstall BF 3 - but the same GDF error xD

Luckily I only have 3 Games that requiring Origin (BF 3, Crysis 3, ME3). The only game which made no problems is Crysis 3, don't ask me why.

@MacCommando  @Danycian

The strange thing about this that it happens on Windows 7 for both of you. 

Please try this:

- Create a new user account with Administrator rights.

- reboot

- logon to the new account and try to install the game.

Thank you for this suggestion.

But there is now a new problem: When I start Origin in the new account, all of my 🏀 Origin Games are not there. It says that the "server is not available" or something. When I switch back to my normal account, all my games appear normal.

I've checked the directories if there are some missing files, but I can't find anything. I also discovered that, when I'am going into my Origin-Account, I don't have any games in here. When I try to add the game via the CD-Key, it says that it is already in use - very strange. I don't see a reason why this should be important, but it should be mentioned.
