LogOnException Error at logon > COMException: No Error

In my program i have the problem that there occurs the error down blow. (LogOnException Error at logon > COMException: No Error)

This happens e.g. on virtual desktops (vmware) with windows 7 32 bit.

On some notebooks with windows 7 32bit or XP SP3 or the developer environment the error does not occur.

In this case i talk about the same report that i have testet. this report works with the same crystalruntime called from the same program, the same way.

The program ist called from a network drive.

there is no firewall that blocks traffic or anything else.

the report works well in the crystal designer.

I actually updated the runtime to CRRuntime_32bit_13_0_4.msi but the error is still there.

the error is thrown at VerifyDatabase().

Here you can download the report mybe it helps http://filex.mcon-mannheim.de/filex/zone/steven.spyrka/-1804743143

var crTableLogOnInfo = newTableLogOnInfo { ConnectionInfo = crConnectionInfo };

Report.SetDatabaseLogon(DatabaseConnection.Username,

foreach (IConnectionInfo iinfo in Report.DataSourceConnections)

{

iinfo.SetConnection(DatabaseConnection.Host, DatabaseConnection.InitialCatalog,

iinfo.SetLogon(DatabaseConnection.Username, DatabaseConnection.Password);

}

foreach (crystal.Table t in Report.Database.Tables)

t.ApplyLogOnInfo(crTableLogOnInfo);

#region Subreports setzen

foreach (crystal.ReportDocument subReport in Report.Subreports)

foreach (IConnectionInfo iinfo in subReport.DataSourceConnections)

iinfo.SetLogon(DatabaseConnection.Username, DatabaseConnection.Password);

t.ApplyLogOnInfo(crTableLogOnInfo);

}

Report.VerifyDatabase();

ReportDbSet = true;

returntrue;

}

return ReportLoaded;

}

This is the code. Did i lose sight of something?
