Eventually the entire catalogue will be converted from installers and will be in Zip format.
There is also an optional installer app on the way, which will need to be downloaded only once, which can assist in downloading and installing the zip files.
However this will optional, you will be able to either choose to use the app, or just download the zips and “do it yourself”.
Once the entire cataalogue is converted there will be no files which are PC speciific or Mac specific, just the one file.
Because of this move, it was decided that there was no real reason to provide an either or option, which would take quite a lot of extra coding, as it wiill ony be for a reasonably short period of time that this annoyance is happening.
Please bear with us, it will be over soon.
