Fix AppVeyor 64bit build

[ax3l]

The CMake Generator line for 64bit build was outdated and does not include the architecture anymore.

Use force to address for the legacy_datasets.tar

Move-Item : Cannot create a file when that file already exists.

I've pushed a fix for the build error, hoping that the CI will pass, if yes, then this looks good. Thank you!
