Thanks for flagging this @Hogardy . We did a W11 test but we’re using TCP binding and deploying as a RemoteApp over RDS, so we’re not trying to install or run the client. The RemoteApps will run on pretty much anything if its screen is big enough, but I haven’t yet managed to get K21 running with RemoteApps.
Just a note to all, Windows 11 testing is being undertaken by the Kinetic team at this time, it is not currently a supported platform for any version of Epicor. We are not expecting major issues, but you never know what will be found. As always upgrade carefully.
