Hello everybody ! I programmed a tool to manage MSDE with SQLDMO. This tool is working properly on my machine where is also installed SQL Server 2000 developper edition. I tried to install all the needed dll for SQLDMO on a machine which doesn't have any reference to nor SQL Server 7 nor Sql Server 2000 but when i try to register the sqldmo.dll with regsvr32.exe i don't receive any message telling me the dll is correctly installed or not and of course my program give this error message : "Class not registered" If someone has an idea it will be welcome ! Thanks.
