------- Additional Comments From saulius.krasuckas@elst.vtu.lt 2006-11-09 03:39 ------- I found {91814ec1-b5f0-11d2-80b9-00104b1f6cea} is referring to ISetupCABFile typelib (or so). This could related to InstallShield problems in Wine. Maybe installing native DCOM and overriding "ole32,oleaut32,rpcrt4=n" would help as a workaround:
