how do you install mass effect 3 from the disc?

Tried to get help  directly from a game advisor at help.origin - but have not received a reply to my emails.

So 6 months after release this problem still has not been fixed and ea help are slow to respond to requests for new codes that will allow origin to recognise the dvd's to install.

I had to manually copy over the files from the discs using the steps below:

1. Start downloading Mass Effect 3 via Origin, pause the download and exit Origin.

2. Delete all files in the Mass Effect 3 subfolder of Origin's game install folder. By Default this is:

C:\Program Files\Origin Games\Mass Effect 3

Also, delete all files in Origin's download cache C:\ProgramData\Origin\DownloadCache\[Your Email Address] and C:\ProgramData\Origin\DownloadCache\

3. Copy the file Mass Effect 3.z01 from disc 1 and Mass Effect 3.zip from disc 2 to a temporary location on your hard drive.

4. Extract these files to the Mass Effect 3 folder in Origin's game install directory. Default

C:\Program Files\Origin Games\Mass Effect 3

(NOTE: Traditional unzipping software such as WinRAR or 7-zip may experience critical errors extracting these files. If this occurs, you can use a program called Total Commander to extract them. In Total Commander some error messages will appear, but these can be ignored)

 5. Remove the read-only attribute to these files and folders (Right Click on the folder in Windows, select properties and uncheck the "Read-only" box).

 6. Launch Origin and resume the download. A small download of approximately 60MB should start to fix missing or broken files. After this, Mass Effect 3 should be fully installed and working.

Once this is all done you then have to download the "Extended Cut" because they didn't get the ending right the first time.
