From where do I import settings from previous version of Android Studio?

Question

I was running Droidio (Android Studio) 0.6.1; from there I was not able to update to the newest version (a quantum leap to 0.8); I had to download it separately and install from Windows Explorer. But now the installation process is looking for old settings:

Where it seems to want to take me is here (to the Android folder, I reckon); this is what I see when I mash the "compressed ellipsis" (one dot) button:

...but I'm not sure that is really the right spot; Is it [not]? What is the precise name of the settings file I should be seeking?

UPDATE

I followed Gabriele's directive, and then I got this:

I chose "Use Android Studio's SDK"

And then I got this when trying to rebuild my project, "Error:Execution failed for task ':app:preBuild'. failed to find target android-19 : C:\Users\clay\AppData\Local\Android\android-studio1\sdk"

UPDATE 2

I then opened the SDK Manager and installed what was missing/out of date, and tried to build again.

I got the error, "Failed to refresh Gradle project 'Platypus' Error: Cause: failed to find target android-19: C:\users\clay\AppData\Local\Android\android-studio1\sdk Install missing platform and sync project

The "Install missing platform and sync project" part of the message is a link. I clicked it, accepted the License Agreement.

Once that finished, the build failed again with a similar message: "...failed to find Build Tools revision 19.1.0 Install Build Tools 19.1.0 and sync project"

Again, the "install..." jazz was a link; I clicked it, accepted, and installed...

The next problem child was, "Error:The project is using an unsupported version of the Android Gradle plug-in (0.11.2) Fix plug-in version and re-import project"

Acquiescing to the counsel of the wise old man in "Never Cry Wolf," I endeavored to persevere by clicking "Fix plug-in version and re-import project"

At which point I finally got a successful build.

UPDATE 3

I then ran the project, and it seemed to be running (it said so, and the red square was visible), but no emulator ever appeared.

I opened the AVD Manager, and the device had a warning icon (repairable). I clicked the "Repair" button; it seemed to work - the warning icon disappeared.

But then I got this:

It still won't display an emulator when I Run > Debug App...

It used to be (with Droidio 0.5* to 0.61) that the first time I ran, I would see this:

...and the Emulator would eventually come up; subsequent runs of the app, the Device would be listed at the top (under "Choose a Running Device") - no more, though - it is only at the bottom as shown in the scream shot above, even on subsequent runs of the app...

I reckon I should try "re-creating the AVD's weird, malformed config.ini" but don't savvy just what steps to take to accomplish that.
