Hi Tammy,
I initially tried installing all 64 bit clients of Design Studio, HANA Client and HANA Studio but 64 bit HANA Studio requires 64 bit java installed. On installing 64 bit JAVA version, I started getting error in WEBI saying "JVM is not installed." so I re-installed all 32 bit version (as earlier I had 32 bit java and WEBI was working fine with it) of all clients and it resolved WEBI error. but I am not able to see HANA ODBC connections.
Also I created ODBC connection using 32 bit ODBC Administrator executable.
Thanks,
Abhijit
