Been there, done that, twice. Need a new, clean download without having to pay again.
Object Dock does NOT officially work for Windows 10 OR Windows 11.
Many years ago the Companies supplying the Weather data started charging for the service at Commercial levels at a price point that would have seen no-one wanting to buy Object Dock at the price level that would have Stardock come close to breaking even.
If you actually are in a situation when a download IS corrupted [here or anywhere else on the net] you will need to shut down the browser...clear cache and reboot, or else you simply get the same error repeated.
Bottom line is...you NEED to ask yourself 'do I really need to use Windows 11?'
The answer genuinely in almost EVERY circumstance is 'NO'.
