I also would like to be able to download 1910. I have 1910.2, but it does not work with our Oracle VM (not Virtual Box) virtual machines. Physical servers seem to be fine. When I try to connect to the VMs, I get a log of messages like "RemoteException: The property 'Product' cannot be found on this object. Verify that the property exists." and a lot of functionality doesn't work. I've seen claims that 1910 is not affected by these types of issues, and I'd like to try it.
Edit: I found the download link on the Known Issues page: https://aka.ms/wacprevious. This currently goes to 1910. I'll update once I determine if it resolves my issue.
Update: After installing 1910, I am able to manage my Oracle VM virtual machines with it with no issues so far. Something in 1910.2 broke this. Hopefully it will be fixed in the next update.
