Using CrossOver 13.0.1 I created an XP bottle, installed Microsoft Media Player Sound Engine 10, then ran the PlayOn 3.8.15 installer. The installer installed the .Net framework and then installed PlayOn. At the end of the installation, it complains that it couldn't configure then firewall, but it still launches the PlayOn settings dialog. The server status goes from "searching" to "initializing" but it never starts. The System check is unable to read the system RAM, and the Antivirus and firewall checks says that there was an "Error detecting".
