DLL (Dynamic Link Library) files play a critical role in the proper execution and running of programs. If such an essential DLL file encounters a problem, it often results in the specific program not being able to start at all. This is the cause of the 'The program can't start because MSVCP100.dll is missing from your computer' error that users could encounter.
Despite the name of the error, the MSCVP100.dll doesn't necessarily need to be missing from the computer system entirely. The file also could have become damaged or corrupted. This specific error also can be caused by hardware issues, Windows Registry problems, or it could be a sign of a threatening activity caused by a malware threat. However, the most common reason for the appearance of the 'The program can't start because MSVCP100.dll is missing from your computer' error is an incorrectly installed or outright missing Visual C++ Redistributable patch that some programs need.
When dealing with this particular issue, the first event is to remember NOT to go looking for places to download a file named MSCVP100.dll. This is an almost guaranteed way to land on dubious websites pushing various PUPs or fake software updates with malware inside. Instead, the solution that works in most cases is to install or reinstall the Visual C++ Redistributable package. More specifically, users should go to Microsoft's official website and look for Visual C ++ Redistributable for Visual Studio 2010 as the MSVCP100.dll file is part of it. Rember to download the appropriate version of the suite depending on whether your computer system is running on a 32-bit or a 64-bit architecture.
