eg.
A 64-bit version is available (within the folder).
A 64-bit version is available (within the zip64 subfolder).
A 64-bit version is available (within the x64 subfolder).
EditPad's installer now automatically installs a 64-bit version of EditPad on 64-bit Windows.
Some of them might not even be applicable to be included in the new field and would still have to be included in the description (eg. when the 64-bit version is included in a subfolder in the package).Installer includes 32-bit and 64-bit version.
So I think it is best to update this on a case-by-case basis and populate the new field only where it makes sense. The other entries can be left as they are.
