Hi,
> I already installed all the Redistributable.
The two packages? for 64 bit AND 32 bit?
Download from
Redistribuable Visual C++ for Visual Studio 2012 Update 4 the two files VSU4\vcredist_x64.exe and VSU4\vcredist_x86.exe then run the two as an administrator then answer Repair even if already installed.
Note : both 32 and 64 bit packages MUST be installed on 64-bit Windows.
> I installed WampServer 32bit and it worked...
So why do not you use it?
64 bit versions of Apache and PHP add nothing more nor even better than the 32 bit versions.
