php_oci8_12c.dll+Unable to load dynamic library (no replies)

Hi to all,
I'm have installed Wampserver 3.1.0 64 bit x64 – Apache 2.4.27 – PHP 5.6.3 in Windows 10 64bit.
I'm trying to enable php_oci8 dll but everytime I'm receiving the followinng error:

[14-Nov-2017 12:57:50 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp64/bin/php/php5.6.31/ext/php_oci8_12c.dll' - ��� ���� ���� �� ���������� � ����������� ����. ������.

in Unknown on line 0

I have tried wiith instant clent 12.2.0.1 for 32 and 64 bit but I got no luck with that.

In php.ini I found this
Use with Oracle Database 12c Instant Client

Which instant client version I need to make it work or what else am I missing?

Thanks a lot
