Does SQL diagnostic manager require full admin permissions all of the time, or is it for certain tasks. After upgrading it looks like admin permissions are needed for connecting to the management service.
For the SQLDM Desktop Client (the .NET user interface), I do believe that it does need to be ran using the "Run as administrator" option. There are a few registry keys that it needs to be able to read and update as well as some config files in the installation directory. I also believe that if UAC was disabled, then you can probably get around having to run the application using the "Run as administrator" option.
