Cannot install Composer because error in Wamp (no replies)

When I try to install Composer this error comes:

PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.6.35/ext/php_cl_dbg_5_6_VC11.dll' - %1 is not a valid Win32-application.
in Unknown on line 0

I have updated all Visual C++ and my Wamp-version is 3.1.3 and it is 64-bit
What have i to do?
