It can happen because of one of the three reasons:-
1) Missing VC++ installation: Install All versions of VC++ redistribution packages VC9, VC10, VC11, VC13, VC14 and VC15. See the link provided at the end for download link. If you have a 64-bit Windows, you must install both 32 and 64bit versions of each VisualC++ package, even if you do not use Wampserver 64 bit.
2) You forgot to provide Admin Privileges to WAMP Server : Launch and Install with the "Run as administrator" option, very important.
3) WAMP, IIS and Skype fighting over same port :
