Java 64 fails when using Launcher

Open a Command Prompt as Administrator.

CD into your C:\Windows\SysWOW64 directory.

Check for any java executables there. There shouldn't be any since the launcher isn't working.

Then type in:

mklink java.exe ..\system32\java.exe

mklink javaw.exe ..\system32\javaw.exe

mklink javaws.exe ..\system32\javaws.exe

And try the Launcher again.
