Re: VC++ Runtime error 1603 unable to install update
Other people have had it, not just for MEA ..

I believe, after much experimentation and digging, I've found the solution.
It appears that the problem stems from the VC++ Redist installs themselves. Origin, by proxy, installs these the three VC++ Redists that are needed to run the game. Unfortunately, not all these VC++ files are compatible with all computers. Attempting to install these files without Origin's assitance results in the program encountering a I/O problem -- error 997. To install DAI, I had to "trick" Origin into installing a version of VC++ that was compatible with my computer.
Here's what I had to do:
Step 1) Go to the Dragon Age Inquisition game folder. Mine installed to "C:\Program Files (x86)\Origin Games\Dragon Age Inquisition"
Step 2) In the directory "__Installer", you'll find a folder called "vc". Inside vc, you'll find 3 folders: vc2008sp1, vc2012, and vc2013.
Step 3) Within each directory are folder's called "redist", and within each of those are corresponding .exe files. Run each of these files.
Step 4) For this fix, you should note that at least one failed to install. You'll need to note which one of these failed, and then search the internet for a version that is compatible. In my case, Origin wanted me to install "vcredist_x64", but this failed. I found "vcredist_x86" was compatible -- installing this onto my computer instead.
Step 5) The last step in "tricking" Origin into allowing you to play DAI, by renaming the working vcredist files as the ones that are found within the DAI "__Installer" directories, deleting the non-working ones and then replacing them with the working ones. I renamed the file I found online (vcredist_x86) to the same name as the incompatible file (vcredist_x64), then replaced the old file with my own.
Step 6) Run the installation again.
The Result:
Origin then is "tricked" into installing the new compatible vc files. Origin is made "happy" because it got to feel like it was in charge and do something useful, and presents the game as being installed and allowing you to play.
