Mass Effect won't install

[FrodoBeutlin88]

I have bought Mass Effect Trilogy. After I've put in the key all three games appeared in Origin and i installed the three games successfully. Mass Effect 2 and 3 work just fine and i have the "play"-button in Origin. The first Mass Effect only shows the "install"-button though it's already installed. When i klick "install", the installation starts and completes but afterwards there's still the "install"-button.

Hey @FrodoBeutlin88, 

Have you changed default instalation folder? Issue might be caused by fact that Origin cant find game files.  

By default it should be here C:\Program Files (x86)\Origin Games

You can also try to manually uninstall Origin, as it might be related to corrupted files.

Hope that helps
