VB Error : Could not load file or assembly or one of it's dependencies

Question

I have project VB.Net. Project had successfully started on Visual Studio 2010. But when it started on Visual Studio 2017, it appeared errors as below.

Could not load file or assembly 'Oracle.DataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Unhandled Exception: System.BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess, Version=4.121.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Please help me to solve this. Thank You!

Did you update your dll without updating your reference in project properties? — muffi, Jan 14 '19 at 07:24
Check the compile options. Did you select 32-bit instead of 64-bit (or vice versa)? — Wernfried Domscheit, Jan 14 '19 at 07:38
Why did you tag "vb6-migration"? Neither VS 2010 nor 2017 supports VB6. — Wernfried Domscheit, Jan 14 '19 at 07:39

There could be several reasons for this error, see https://stackoverflow.com/questions/659341/the-provider-is-not-compatible-with-the-version-of-oracle-client#25412992 — Wernfried Domscheit, Jan 14 '19 at 17:38
