I installed wamp server 2.5 in my windows 8 laptop but during the process I got error of missing msvcr110.dll. So I googled and found out that some redistributable can be installed from microsoft and then wamp server functions properly. But to my surprise even after that it did not function properly showing the tray icon in yellow where I could not even click.
After googling for 150 links and trying all processes for 4 hours, I permutated a way to solve this issue. First I had to uninstall wamp and remove all the wamp references and then had to download 2 dlls
1) msvcr110.dll
2) msvcp110.dll
After that I copied them in "C:\Windows\System32". Now I installed the 64 bit wamp as my Laptop is 64 bit. This time I installed wamp without any errors. Even the wamp icon in right bottom tray is green.
