Hi, Is it possible to use 2 versions of the odbc driver simultaneously on the same windows machine? Since the windows installer does not allow this, I copied the installation folder from another machine and register the driver using the following command: odbcconf /A {INSTALLDRIVER "MonetDB ODBC Driver Old|driver=C:\Program Files\MonetDB\MonetDB ODBC Driver Old\lib\MonetODBC.dll|Setup=C:\Program Files\MonetDB\MonetDB ODBC Driver Old\lib\MonetODBCs.dll|APILevel=1|ConnectFunctions=YYY|DriverODBCVer=03.52|SQLLevel=3"} In the registry and the ODBC datasources the driver "MonetDB ODBC Driver Old" is registered correctly, but when I try to create a DSN for the new driver I am getting Error "Invalid Driver name". Does the Monetdb odbc driver need to have the exact name "MonetDB ODBC Driver"? Thanks.
