Hello @chowsp ,
We are assuming you running Replicate on Windows, so besides @SachinB suggestion, please make sure:
1- if you installed the ODBC driver after Replicate installation, then please restart the Replicate services (via Windows Service Management) and try again ;
2- please make sure you download and install the 64-bit. Replicate cannot work with 32-bit driver.
Go to Snowflake download page https://developers.snowflake.com/odbc/ and use the 64-bit one:
3- Add the ODBC installation folder (default "C:\Program Files\Snowflake ODBC Driver\Bin") to system variable PATH, then restart Replicate services again (but personally I do not think it's necessary).
Hope this helps.
