Questions:

Can Bitcoin Core installation on Computer #1 be fixed?

Why is there no APPDATA/Roaming/Bitcoin directory after installing Bitcoin Core on Computer #2?

What are some options for my wallet.dat file to recover the funds whether with Bitcoin Core or another local or web client, keeping in mind I have the wallet.dat, but can't start Bitcoin Core anymore.

In Bitcoin Core on your #2 machine... Goto: "Help -> Debug Window -> Information"... and see what the "Datadir" value is. This is where your blocks folder will be and where you need to out the wallet.dat file.
