Error on install - undefined function mb_detect_encoding (2 replies)

Everything went so smoothly on install.
Everything fired up ok except I get this error when trying to get to phpmyadmin


Fatal error: Call to undefined function mb_detect_encoding() in W:\wamp64\apps\phpmyadmin4.6.4\libraries\php-gettext\gettext.inc on line 177


Installed in it's own partition and everything starts up. I spent 2 hours reading through the sticky posts and some other trouble shooting but havent' seen the exact error turn up in a search.

Also getting this

** ERROR *** The PHP configuration loaded file is: - should be: W:/wamp64/bin/apache/apache2.4.23/bin/php.ini or w:/wamp64/bin/php/php5.6.25/phpforapache.ini
You must perform: Right click - refresh....

the phpforapache.ini file is there. refresh does nothing

Able to get a virtual host up.

PhpSysinfo is also not working because of the mbstring extension which I'm sure is also related...

Any help would be greatly appreciated!!!!


State of services:

The service 'wampapache64' is started

The service 'wampmysqld64' is started
