Run Origin as Administrator. > test the installation again.
If that don't works, I would suggest to create a folder named "Origin Games" in the root of your D drive.
- Set the "Game Library" to that folder. (In Origin, menu top left corner > Origin > Application settings > Installs & Saves > On your computer > Game library location > navigate to the "Origin Games" folder > apply.)
- close Origin completely.
- rename the "Mass Effect 3" game folder under "BigGames3" to "ME3".
- Start Origin and start the download of ME3 > pause the download after 30 seconds.
- Copy all files from inside the "ME3" folder into the newly created "Mass Effect 3" folder inside the "Origin Games" folder. (override) / (So you don't need to download everything again.)
- Start Origin as Administrator > Game Library > ME3 > Download > Origin will verify the data and should install the game properly.
Interesting solution. But ... it doesn't work. Why should that anything change if I rename some folders?
Only difference is the other folder names in the InstallLog.txt:
11:18:46 Installing GDF ...
11:18:46 Installing D:\Origin Games\Mass Effect 3\GDFBinary_de_DE.dll ...
11:18:46 Alternate GDF game name Mass Effect 3
11:18:46 IGameExplorer2 for windows 7

I will undone this, because this folder-architecture is not in my interest and the error must be anywhere else.
Bevore this error I have got a problem with the "DirectX-Phase". The installation aborted there. But I could fix this.
Furthermore there is an entry in the InstallLog that could be helpful:
11:18:32 Processing EAIN file 'D:\ORIGIN~1\MASSEF~1\__INST~1\Touchup.dat'.
11:18:32 Installation registry missing. Game not yet installed.
Maybe it would be anything changed if I manually add these entries? What are these?
Because this is most probably a permissions error and creating a new directory by hand under your account was wohrt a try.
I assume you use Windows 10 1607 as OS because I heard of this error most often on this version.
I am pretty sure that installing the game to your C drive would work without problems, if you could test this it would help to isolate the problem.
If you use a diffrent OS or OS version 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.
