WinRAR is a software application that extracts compressed archive files. A cyclic redundancy check error, or CRC error, results from one or more damaged files within an archive. When you attempt to extract a partially corrupted archive, WinRAR may display a CRC error and prevent you from accessing any of the files in that archive. The software includes a built-in feature that allows you to bypass this error. A CRC error may also appear when you attempt to install the WinRAR software after an incomplete download. If this occurs, redownload WinRAR and attempt the install with a complete download of the set-up program.
