I have installed Wamp server, but when try to launch it, the taskbar (orange) icon indicates that its "offline".
- I have tested port 80, it seems that it is not being used and IIS is disabled.
- The "Start" and "Stop service" options under Apache, are grayed out (disabled).
- Install the C++ Redistributable Package 2010: here.
- If the problem isn't solve yet simply download the missing msvcr100.dll file and place it in C-> Windows-> system 32
