------- Additional Comments From rob@codeweavers.com 2006-09-07 13:59 ------- The log has the following lines in it that indicate roughly where the error is coming from: trace:ole:_invoke Calling 0x414f93(b7d04828,00000000,) trace:ole:WINE_StringFromCLSID 0xb7d04ab5->{821DABD6-26F2-49E5-AE55-40A589ADBE6D} trace:ole:_invoke returns 8000ffff
This is during a call to ISetupCABFile::InitializeLog in InstallShield.
I think a relay log will be necessary to identify why this call is failing.
