I have Mercurial 3.2.3 installed as part of the installations which was done at the time the PC was built
I updated to Mercurial 4 as the System version
Try selecting Use System Mercurial and the dialog pops up about the old version and after clicking ok nothing happens
Try to update Embedded - Machine is behind a proxy; proxy settings are correct and I get a Proxy authentication required error after putting in proxy details to the dialog which pops up. Went through resetting proxy password in general configuration and it still fails.
