My computer rejects the download of Syn3 Updater

That’s odd… Once you click on that, the following page should display a “loading bar” like this:

Once it gets full, the EXE should be automatically downloaded without further interaction.

Where does it exactly fails?. Also, if the file you download is like the one I’ve sent just above, you can ignore the warning.

From what you are saying, you are likely to be running 3.4.22251 or 3.4.23088. Those builds have a bug in which a partition gets full, which causes what you are describing. You need to get out of that build.

All known methods for resolving it are described here → APIM Sync Settings Not Saving, VER_ERR08 Errors, Cannot Perform Master Reset or Upgrades/Updates (Solved)

You do not technically need Syn3updater for that, but it’s highly recommended so that the USBs are created automatically.

By the way, can you download this ?

Please confirm since this is just a temp upload to get you going.
