I am trying to run the current client and the 6.2.2 client (unzipped rather than installed) side by side, since we can't upgrade our two pre-existing servers yet. Other than some visual anomalies they seem to work fine that way, except that both of them seem to read the location for the settings directory from HKCU\Software\VisualCron\ClientSettingsPath, so my attempt to set up separate directories for them didn't work out as well as I had hoped. I can work around that, but I wanted to check first and make sure there wasn't a simple way built into the client already.
