The problem is not the installer, it's the Couatl.exe, which is downloaded automatically by the installer so, it's not relevant which installer you have, since they will all download the current Couatl.exe.
That's why you don't have to worry about checking the version yourself, or even *wondering* which one is the latest: just run the installer again, and it will download the most current version of the most important files, the one which is current the moment you run the installer.
I checked the version you had by looking at your report, which show you weren't using the latest version, surely not when you posted the error log.
If you still have errors with the current version, then please post an updated error log.
