When running a certain program (most often games), errors appear in the form of dialog boxes with system messages. For example, a window with the message “The program cannot start because msvcp100 is missing. dll" occurs when running software developed using Microsoft Visual C++. To easily eliminate malfunctions of this kind, you need to study in detail the causes of their occurrence and develop a template that will help avoid mistakes.
Software Details
To organize a dialogue between a person and a personal computer (PC), software is used. Without software, a computer cannot calculate even a simple expression, for example, 2 + 2. At the initial stage of loading the PC, control is intercepted by the BIOS (basic input and output system), and it is at this stage that the PC hardware is converted into logical (software).
For example, a microprocessor (CPU - central microprocessor) is a logical device, although in fact it is an ordinary microcircuit. The computer uses the binary number system (initially) , and later, in operating systems such as Windows, the hexadecimal number system is used (for example, references to RAM addresses).
The software performs various functions and therefore experts have divided it into main types:
- Operation mode (main software capabilities).
- Scale of application (various projects requiring a large number of developers, or individual application).
- Stability (software operation implies the use of stable or testing versions).
- Functionality (processing text data, compiling applications, processing or creating videos and other functional applications).
- Protection (the ability of the software to resist attacks from Internet criminals and ensure the security of the user’s computer and his personal data, for example, the password for the mailbox to which an important letter was received).
- Reliability (the likelihood of a few system bugs during operation, as well as the support and availability of updates that improve the relevant software to reduce this likelihood).
- Performance characteristics (software system requirements for PC hardware and software).
- Source language of writing (the language in which the software was created).
- Applied area (application in financial, medical, scientific and other highly specialized areas).
- Computing system and environment.
- User class (user level: beginner, intermediate and expert).
- Criticality (examples: national security, human life).
- Readiness (possibility of immediate use).
- Provision and use of data (presence or absence of data encryption).
- Industry sector (software is developed to order, used for corporations or for consumption by ordinary users).
- Platforms: platform-dependent (developed for one platform, for example, Windows 7) and cross-platform (can be used for the Windows OS line).
- Distribution method: paid (to use you need to buy the software), shareware (the user is given a trial period for testing the software with all the features - full functionality. However, after this period the program becomes with limited functionality) and free programs (free - free use) .
- Purpose: system (used to perform various system functions, for example, clearing the registry of incorrect parameters and keys) and application (software for drawing, drawing, programming and typing, and other areas).
- Types: component (for example, a dynamic library file) and a complex (example: a set of dynamic libraries for running the desired program).
Purpose of Windows software
To understand the architecture of the OS software environment, you need to know the main purpose of the software. As you know, software can be system or application by purpose. In addition, there is a 3rd group, called instrumental (will not be considered).
System software provides a comfortable user experience and performs a number of low-level functions, for example, saving a document by writing it to the hard drive.
After all, the user does not take part in this process, he only gives the appropriate command. System programs help monitor system status, such as the registry. Even the operating system itself is a system program.
The division of system programs into groups is conditional: operating systems, utilities (maintaining and expanding the capabilities of the OS), drivers (ensure the correct operation of the hardware), operating shells and file managers.
The registry consists of system files that increase in size as software is installed and uninstalled. But this information does not disappear anywhere, although it is superfluous. For example, a user installed a game and played it. For some reason he didn't like it and deleted it. This information is stored in the registry. When the OS boots, basic parameters and settings are initialized, drivers and libraries are loaded, but registry files are also loaded, making loading slow and work less comfortable.
The basic principle of building the software part is shared resources for the software. This aspect has positive and negative sides.
The first include the following: when writing a program, developers do not completely write all the libraries, packages and drivers for correct operation, but believe that they are present in the OS or can be downloaded and installed. Why write DirectX if it is already in the system?
The latter includes the possibility of “cluttering” the OS - the registry, disk space and RAM. This clutter leads to slow operation of the entire system. However, you should also take into account the fact that if the optimization program accidentally deletes a dynamic library, the rest of the software may malfunction.
Application software includes programs that perform certain tasks on a PC. When installing this software, sometimes errors occur during the installation process or during startup.
This is mainly due to several reasons: lack of necessary files and libraries, low characteristics of the PC itself, virus infection, version mismatch, low-quality software, access rights and a number of other reasons.
Solving msvcp100.dll error using Visual studio
As I described above, the file that is missing is a component of the Visual C++ 2010 package, so the surest solution is to reinstall the entire package. In other words, in order to download msvcp100.dll to your computer, you just need to download the Microsoft Visual C++ 2010 package and install it on your PC. The program will automatically copy the files to the windows system folder and register them. You won't have to do anything else.
I can suggest a universal way to overcome this error, download from our website and install all microsoft visual c++ packages in one file:
You can download the Microsoft Visual C++ 2010 redistributable package from the links below in accordance with the bitness of your operating system.
Uninstalled libraries
Situations arise when it is impossible to install the necessary software. This is due to the lack of files needed by a particular program. During installation, the parameters are initialized and the necessary shared resources are searched in the form of separate files with the dll extension. This type of file is called dynamic library.
Errors that occur during the installation or startup process can be different, but in most cases a dialog box pops up, which carries information about the inability to install or run the software due to the absence of a certain library (for example, the absence of the msvcp100. dll file (mscvp100.dll) or msvcr100.dll for windows 7).
The main reasons for these system errors can be missing files, missing required packages, file system corruption, computer virus infection.
How to update DirectX - a method that does not require Internet access
In the absence of Internet access, installing and updating DirectX is somewhat difficult.
The easiest way is to take the disc with the game you already have and during the installation process, check the box for installing add-ons, which quite often includes DirectX. You can subsequently delete the game itself - the installed or updated DirectX will remain in the system.
You can also use a utility whose task is to update drivers. It often contains the latest updates for DirectX.
Solutions to the problem
What to do if the error is msvcp100. dll on Windows 7 is a common question that PC users encounter. First, you need to analyze the elimination methods and select one of the optimal ones. To resolve the problem associated with a missing file, you need to look at a specific example.
The user installed the game on Windows 7, there were no problems during installation. If a system error occurs when starting the application, the program cannot be launched because the msvcp100 file is missing. dll (mscvr100.dll), then there are several ways to fix the problem:
- Downloading a library from the Internet.
- Installing the appropriate package.
- Recovering system files.
The easiest way is to download the library from the Internet. You just need to enter the name of the library in the browser search engine (for example, chrome), for example, “msvcp100. dll for Windows 7". Then select the file and download it to the hard drive (hard drive) or any storage device, drop it into the desired system folders of the current OS.
But before you figure out where to throw the file and search for ways to register it, you need to find out the positive and negative aspects of this method.
- The positive ones include the following: simplicity and speed of resolving the issue.
- Negative : possible mismatch of file versions; registration of components (if necessary); the presence of malicious code added by a hacker; linking with the registry and eliminating system errors.
This method is suitable only for experienced users, which means it is not suitable for beginners. Although most confident users do not use it, but prefer installing the appropriate package.
Installing the Microsoft Visual C++ package is the best solution. The user does not need to search for the library on the Internet, but simply needs to install the package, and the problem is solved. You should pay attention to the bit depth of the system and the package (they must match). Then start downloading.
The installation is simple, but there are times when for some reason it is impossible to install this package. The main one is the outdated OS. In this case, you need to update the system by downloading the necessary add-ons or do it automatically. After this, re-run the installation of the Microsoft Visual C++ package.
The third method is used very rarely. Used when components of the Microsoft Visual C++ package are accidentally removed. However, it is better not to use it, but to clean the registry and perform the installation again.
For Windows 10 OS, the solution is the same, but you need to download the latest version of 2020 and install it.
How to download and install MSVCP140.dll
You can download msvcp140.dll as part of the Microsoft Visual C++ 2020 components, we recommend from the official Microsoft website using this link: https://www.microsoft.com/ru-ru/download/details.aspx?id=53840.
Instructions:
- Step 1: Select a language
- Step 2: If we have 64-bit Windows, mark both x64 and x86 (necessary), if 32-bit, then one x86. Download to PC;
- Step 3: First of all, run the installation file vc_redist.x86.exe , secondly - vc_redist.x64.exe .
After successful installation, the msvcp140.dll file will be present in the system (look at the folders C:\Windows\System32\ and C:\Windows\SysWOW64\) and we will be able to launch new games or new programs on the computer without a message that the program cannot be launched , because msvcp140.dll is missing on the computer.
Universal algorithm
For such cases, it is possible to use an algorithm that is based on generalized methods for eliminating problems associated with the absence of important files:
- Purpose of the file.
- Determine whether a file or library belongs to a specific package.
- Download the package. In this case, you should pay attention to the OS architecture (32 or 64 bits).
- Installing the package. If this does not work, then you need to find and download updates for the OS.
- Reboot the PC and check for OS system errors.
If this algorithm does not help, then the reason lies in the file system being damaged or infected with a virus.
What is this error?
The msvcp100.dll error is due to the absence of a library of the same name with a set of instructions in your operating system.
But the error can also be caused by viruses that have damaged it! Try to always use a computer with an antivirus!
Attention!
It is strictly not recommended to download dll files on sites where it is proposed to solve this problem, these files may contain viruses, this is how they are most often distributed! The problem can be solved officially!
