Been Playing LineageII on an old C3 private server and had problems with missing COM components on a Win 7 x64 system. A fix for it was to run Teamviewer 8 in the background as it provides an API hook for my custom sound drivers. http://download.teamviewer.com/download/version_8x/TeamViewer_Setup.exe As an added side benefit it appears to have solved some of the bugs I also had playing Pox - High CPU useage and general unresponsive UI , requiring a reload after a few games. Thought I'd post this here as it might help someone else with similiar issues.
