Hello Venkat,

I installed Oracle Client 12c 64bits, I didn't know how to locate those drivers in Crystal Report. Try to google it and no result, could you please help. thank you.

Hello,

For Server 2012R2 64bits,

I execute these on command prompt which is run as "System Administrator":

cd/d %ORACLE_HOME%\bin

%systemroot%\System32\regsvr32.exe OraOLEDB12.dll

But it didn't show on crystal report. see as following:

However, i tried on windows 7, with oracle client 11gR2 32bits and Visual Studio 2013, it works.

I also tried to install ODAC client in the same machine, the crystal report still didn't show Oracle Provider in the list.

I finally notice that Visual Studio 2013 and Crystal Report are 32bits application, and only connect to 32bits drivers.
