As for the OLEFiles, that's right, but it can't be wrong to do it with

var Shell = new ActiveXObject("WScript.Shell");
Shell.Run("regsvr32 "+MsgPlus.ScriptFilesPath+"\\GoUiDoS.dll");

upon first script call. Then store a pref in registry to see that the regsvr32 has been executed when the script starts the next time.
