Installed 8.2.4 over 8.2.2 today, no problems. Have to say, I like the new installer, less of the bumping & grinding than the old AC installers. Still -- a few command line windows appear -- a little scary when doing a weekend install.
In any case, opening & closing charts isn't perceptibly faster. YMMV, to quote Indy.
This reminds me that I need to go find Mel's response, and answer the question about the YMMV.
Our observation is that the higher the number the users in an upgrade, the more challenging the upgrade can be. YMMV
