WinRAR is a popular software for compressing and extracting files. However, sometimes you may encounter a diagnostic message error when you try to open or extract a file with WinRAR. This error can be caused by various reasons, such as corrupted or incomplete files, wrong password, damaged archive header, or incompatible file format. In this article, we will show you how to fix WinRAR diagnostic message error with some simple steps.
Step 1: Check the File Integrity
The first thing you should do is to check if the file you are trying to open or extract is complete and not corrupted. You can do this by comparing the file size and checksum with the original source. If the file size or checksum does not match, it means the file is corrupted or incomplete and you need to download it again from a reliable source.
If the file you are trying to open or extract is password-protected, you need to enter the correct password to access it. Sometimes, the password may be case-sensitive or contain special characters that you need to type exactly. If you forget or lose the password, you can try using some third-party tools to recover or remove the password. However, this is not guaranteed to work and may take a long time.
Step 3: Repair the Archive Header
Sometimes, the archive header may be damaged due to virus infection, power failure, or improper operation. This can prevent WinRAR from recognizing the file format and cause a diagnostic message error. To fix this, you can use the built-in repair function of WinRAR to repair the archive header. Here are the steps:
Right-click on the file and select \"Open with WinRAR\".
In the WinRAR window, click on \"Tools\" and select \"Repair archive\".
Select the repair mode and the destination folder for the repaired file.
Click on \"OK\" and wait for the process to finish.
Open or extract the repaired file with WinRAR.
Step 4: Convert the File Format
If none of the above steps work, it may be because the file format is not compatible with WinRAR. For example, some newer versions of ZIP or RAR files may not be supported by older versions of WinRAR. In this case, you can try converting the file format to a compatible one with some online or offline converters. For example, you can use Online-Convert.com to convert various types of files online for free.
