error installing PHP7 plugin (no replies)

I'm stuck on the install of the PHP7.05 for wamp 3.







I'm logged in as superadmin, and wamp is clearly installed on c:/wamp.

these files are in c:\wamp\
wampmanager.conf
wampmanager.exe
wampmanager.ini
wampmanager.tpl

In wampmanager.conf:

installDir = "c:/wamp"

I'm sure I'm in the right directory.

This is on windows 10 64 bits.
