Microsoft Visual Studio installs a process called Microsoft C Runtime Library. This is an essential file that contains modules needed to run programs that were written with Microsoft Visual Studio. The file is located in the Windows folder of your system, usually in drive C. File size largely depends on the version that you installed. Usually, file size is between 626,688 and 633,696 bytes. There are certain applications that fail to execute when invoked because the file msvcr80.dll was not found. Typical error messages may read “This application has failed to start because msvcr80.dll was not found. Re-installing the application may fix this problem.” In some instances, the error message is displayed when a plugin or add-on was installed for the specific application. On occasion, the file msvcr80.dll has been detected as a carrier of harmful modules. Installation of some software may have altered the msvcr80.dll file, and in doing so, injected modules that could be a risk to the system’s health.
