Re: i have created a new ODBC connection 64 bit and 32bit using SQL server 2014. On the new connection, the report is running fine on the rich client, but it gives database error on BI Launchpad, how can i diagnose this problem?

Assuming this is Webi or Crystal for Enterprise (not "classic" Crystal), the rich client will use the 32-bit connection and BI Launchpad will use the 64-bit one.  So, it looks like the 32-bit ODBC connection is correct but you're missing the 64-bit connection.  Do they both have exactly the same name?  Is it possible that you have a typo in the name of the 64-bit connection?
