I've downloaded the drivers, tried creating 64 bit DSN's, none of it makes any differennce
Plus, the crystal api is being called from a COM application that has no trouble making its own database connection using the sql driver version 6 for sql server, or the 64 bit oci library for oracle.
I have found that in the 64 bit code,, I also need to set tableLogOnInfo.ReportName before applying it to each crystal Table, otherwise the settings don't actually get applied in the table.So perhaps I am missing some other bit of code that is required to make this work in 64 bit, that wasnt necessary in 32 bit.
