Install Oracle Client 12c on Windows 10 – INS-20802: Oracle Net Configuration Assistant failed

Hello all!
Some days ago a client reach me because he was facing this error when installing Oracle Client on Windows 10:


Researching on topic found this.

Seems Oracle client requires MSVC 2010 redistributable to proceed Oracle Net Configuration step.
After this requested client to install “Microsoft Visual C++ 2010 Redistributable Package” on server. And issue solved! 🙂

The download of Package can be performed from here:

Hope it helps you!
See you next week!
