There is a bug related to the xampp version, that is, x86 or x64 bits.
"I have a system with x64 bit windows and I installed a xampp with php7, but it was x86. This was one reason for this error, apache failed.
Now I have separately installed apach2.4 (x64) and PHP7.0.1 which is working perfectly now. "
