How to rectify DLL Errors like MSVCR71.dll was not found or MSVCP71.dll was not found or any dll was not found?


Have you received the following DLL error messages when try to install a program?

The application has failed to start because MSVCR71.dll was not found.

The application has failed to start because MSVCP71.dll was not found.

The application has failed to start because xxx.dll was not found.

I think everyone has received this type of messages. We can rectify this type of messages very easily.

First I will explain what is a DLL file and it's uses. Then I will give the solution to the above type of dll error messages.

A dynamic-link library (DLL) is a module that contain functions and data that can be used by another module. Module can be another DLL or a Windows application. A DLL can be used by several programs at the same time. Windows operating system provides some DLLs. Some DLLs are particularly written for a application and these DLLs are loaded with that particular application.

DLLs save memory, reduce swapping, save disk space, upgrade easier, provide after-market support, provide a mechanism to extend the MFC library classes, support multilanguage programs, and ease the creation of international versions. DLL file will be loaded in to RAM when a program needs it only. Thus DLLs save memory. It saves Disk space since same DLL is used by several applications. If each application has it's own DLL then a lot of space is required.

Rectification of DLL Errors:

If you get the application has failed to start because MSVCR71.dll was not found error message, then you have to download MSVCR71.dll zip file. Then extract it. Then copy MSVCR71.dll file and paste it in Windows/System directory.

Download MSVCR71.dll

If you get the application has failed to start because MSVCP71.dll was not found error message, then you have to download MSVCP71.dll zip file. Then extract it. Then copy MSVCP71.dll file and paste it in Windows/System directory.

Download MSVCP71.dll

Other DLL Errors:
If you get any other dll errors then just goto the above site http://www.dll-files.com. In that site you will find Search for DLL Files. Just type the DLL you want in the box, then click O.K. Now it will display that DLL informaton. On the same page you will find the download link for that DLL file. After downloading the DLL file paste it in Windows/System directory.
