SSIS Oracle 32 bit error "Invalid access to memory location."

My SSIS extracts data from Oracle DB and loads into the excel file. I am running this package via SQL Job. Now to use Excel providers I have to use 32 bit environment. So I've changed the SQL JOB execution to "Use 32bit runtime".

But now my oracle task is failing with error "Invalid access to memory location."

When I don't use 32bit runtime in job, the oracle task works but the excel task fails.

We have both 32bit and 64bit Oracle installed on the server. So not sure why oracle task is failing in 32bit environment.

Any help will be appreciated. Thanks in advance.
