How to troubleshoot the checksum error winrar?

That usually means the file is either corrupted or didn’t download properly.

Try this:
  1. Re-download the file — most of the time it’s just a bad download.
  2. If it’s in parts (like .part1.rar, .part2.rar), make sure all parts are downloaded and in the same folder.
  3. Try using the “Repair” option in WinRAR — right-click the file > Repair archive.
If none of that works, the file might just be broken.
