[EA app] Can't Install Mass Effect 3

I've also tried installing it without any DLC and I get the same error with just the base game.

Try to run EA app as Administrator.

Same error

@it_is_oz 

Go to your "...\Mass Effect 3\__Installer\directx\redist" folder.

Delete all files with a "*.cab" file extension. (Only the files with a "*.cab" file extension.)

Run the "DXSETUP.exe" from the same folder as Administrator (right click the "DXSETUP.exe" > Run as Administrator.

Restart your PC > Test.

So I've tried this fix before and it didn't work; but I'm willing to give it another try. Before I do, though: should I cancel the current installation that is failing and retry the whole download, or should it be fine just hitting the 'retry' button and seeing if it will work? Or both?

I guess this question applies to the previous suggestion, as well all future attempts. I'll cancel the install and try the administrator privs for the EA app with a fresh download while I wait for a reply. Will update with results.

EDIT: Same error after cancelling the the installation, running the EA app as an administrator, and trying to download it again. I'll go ahead and start try your latest suggestion both ways as well.

EDIT2: Deleting the .cab files, running the DX setup, restarting computer, then trying to resume the download did not help. Same error occured. Going to try a fresh download as an administrator. Will update again after this next test.

EDIT3: Same result even after doing the whole process again as an administrator the entire way.

1. 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.
   
   
2. Go to your Mass Effect game directory and then to the "__Installer" folder (Standardly: "C:\Program Files\EA Games\Mass Effect 3\__Installer\) and upload the "InstallLog.txt" as well.
   
   
3. Hit Windows key and X.
   Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” or "Windows Terminal (Administrator)", whichever option is offered.
   Inside the PowerShell or CMD, enter “DISM.exe /Online /Cleanup-image /Checkhealth” without quotes. > ENTER.
   If errors are found, notify us. If no errors were found reaped steps 1 & 2.
   Inside the PowerShell or CMD, enter “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes. > ENTER.
   The system will start validating soon. If it throws an error, please list it here.
   After it reaches 100%, hit Windows key and X again.
   Again, choose “PowerShell (Administrator)” or “Command Prompt (Administrator)”
   Inside the PowerShell or CMD, enter “sfc /scannow” without quotes. >ENTER.
   Post the message you receive at the end of the processes here.

Alright here we go, sorry for the delay. I forgot all about checking this after work last night.

Attached are the DxDiag and InstallLog text files. Also attached is a screenshot of the DISM from the command prompt. It said it had a log file but there was a ton of stuff in there dating back several years so it seemed silly to upload the whole thing -- but I can do so if required.

Thanks!

EDIT: I don't want to speak too soon, but I might have solved the problem myself. Will add a new reply if it turns out to be true.

Okay!

So it isn't the ideal fix that I was looking for, but the game is installed and I was able to connect to the multiplayer so I am THRILLED.

I don't know how I never thought of it before now or ran across a suggestion to try it, but I tried to reinstall the game on my windows drive instead of my game drive. (so C: instead of E: )

The game installed fine and all of the DLC kind of worked. The From Ashes DLC completed successfully, and then somehow failed at the end of the process even though it was listed in the 'completed downloads' section. I just cancelled that failure, so far everything works fine though.

I hope this helps someone else, though I still wish I would've been able to keep it on the same drive with all of my other games.

Unfortunately my wife is still receiving the same error despite having gone through all of the steps I took to reach my solution. Her PC has the exact same specs as mine. Why can't anything be simple?

I'll post her DxDiag/DISM/InstallLog stuff in just a bit after she finishes up what she's doing.

Alright here is all the info from her side. Her DISM process yielded some errors that were then corrected, so I'm trying the installation again for her now.
