Thank you.
Instructions from 1st post worked like a charm (besides a few edits).
I installed php7.0.2 on some 2.5 wamp server.
Changes were:
1. my wamp /scripts/config.inc.php had different layout for $icu array (the individual names were separately added in the array)
2. for php7.0.2 the dll's end with 56 not 55 (eg icudt56.dll)
