Apparently, POL uses the default system version of wine unless otherwise specified, so I was in fact using Wine 1.5.3 -- which doesn't work. What really caused me to waste time was that the default version of Wine in the Ubuntu repo is 1.4.0 -- which for some reason doesn't work whereas the 1.4 that comes from POL does!!! So to summarize: 1) Use POL and use it to install Wine 1.4 and it will Just Work with EN-4.5.4 2) Do not use the Wine 1.4.0 from the Ubuntu repo. 3) Wine 1.3.0 -- installer crashes.
