I got an httpd.exe system error running wampserver using Windows 7 or Vista because of MSVCR100.DLL is missing from the computer.
In order to resolve the issue you can download the geniune MSVCR100.DLL for Windows vista or Windows 7 here:
http://www.archiemercader.com/downloads/msvcr100dll.rar
After download, extract the MSVCR100.DLL file to the c:WindowsSystem32 (32 bit) or c:WindowsSysWOW64(64bit) then I advise to restart your PC to take effect.
Any more questions? just let me know or just leave some comments below.
THANK YOU SO MUCH
your welcome Angel, im glad to be of help!
