fix: Add error handling if default EA App path (#211)

* fix: Add error handling if default EA App path

We cannot install to
`C:\Program Files\EA Games\Titanfall2`
cause Windows™

As such if install fails we check for that path and show according error
message

* fix: Check only for `Program Files` path
instead of the full one

As the issue is technically the permissions with `Program Files`, not
the EA Games subdirectory...

* fix: Format check error
