The tool's server configuration store is not stored in a atlas server manager folder, its configuration exists in the registry, there are more than 30 servers, you just need to add 30 in a atlas server manager. Do not try to copy more than one atlas server manager
Today, my atlas server manager 2.9, did not update to 10.43 as normal, it does not show updates.
And I now change it to 3.0. It's updated. Provide a screenshot, I don't know if I can provide some information.
