Error during transferring a file to the watch

suddenly i got this message when transfering a file to the watch.
already installed new Java. any idea what the problem could be?

I am getting similar message when i try to transfer a watch face on my watch that already exists with a higher version and try to replace it with lower. So check the binary version is higher or equal and not lower than the one on the watch.

indeed, replacing a older file does not work even, but this is a new file , not on the watch already. but there was a update for the watch software a few days ago so that could be the problem.
but no idea how to solve that, wait for a update of the watch studio?

It is not unheard of that an update will required a new Distributor Certificate for installation. Create a new one and you should be good to go.

thanks, i created a new distribution certificate, rebuild the file and ik works.
