I have been slow about updating PM 4.5.3.1 to 4.5.3.2. Now I'm getting to it, and on launching the 4.5.3.2 installer, I noticed that it doesn't seem to know where I had installed 4.5.3.1 on this machine. Can multiple versions be installed on the same machine? If that isn't a good idea: should the currently installed version be UNinstalled first? If not, then I can just point the installer to the directory containing 4.5.3.1. Will the 4.5.3.2 installer again need to know the registration number? (If so it would presumably be the same as was used during the first installation.)
Thanks.
