Recently, when installing Wampserver, it was prompted that msvcr100.dll was missing from the computer, resulting in unsuccessful installation. I will record the solution and hope it will be helpful to everyone. This solution is also from Baidu on the Internet.
Step 1: Uninstall the unsuccessful Wampserver.
Step 2: Download VC10, the following is the Microsoft official website VC10 link:
VC10 SP1 vcredist_x86.exe 32 bits : http://www.microsoft.com/download/en/details.aspx?id=8328
VC10 SP1 vcredist_x64.exe 64 bits : http://www.microsoft.com/download/en/details.aspx?id=13523
Step 3: After installing VC10, restart the computer.
Step 4: Reinstall Wampserver.
