Welcome to the Legacy Uploader.
This is now out of date but will continue to operate for the next couple of months so everyone has a chance to update to the new system.
It does not work with the Online Editor and accounts are seperate.
The latest version of the Windows Editor has a new option to export data from it, ready to import into the new Online Editor and is available below:
Ministry Maps Editor v1.0.0.exe
The old help video is still available here.
See this new guide on using the Old Windows Editor to export data to the new Online Editor.
Note, there is a filesize limit of 16mb. If your .zip folder is above this it won’t work, a useful site to shrink image filesizes without losing quality is TinyPNG.
