Answer 1

I developed desktop application using C#.net with 2.0 framework along with system.data.oracleclient for connecting oracle db and I was facing similar error message ,"Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed."

following solutions were applied

• Project, properties, Build TAB, select platform target : x86
• Project, clean build, ReBuild solution
• Install Oracle 11G*32 bit client

now, it work because application is set for 32bit and oracle 32bit client installed over Win2012 R2 server, hopefully will work for you.
