First-response checklist
- 1Check the file sizeCompare it to what the source page listed, if known. A file much smaller than expected likely downloaded incompletely.
- 2Re-download from the original sourceA surprising number of archive problems are actually download problems. This alone fixes many CRC and corruption errors.
- 3Confirm you have an extractor installedSee WinRAR download or, on Mac, RAR tools for Mac.
- 4Look inside without extracting, if unsureThe archive inspector reads the header locally and can confirm the archive type, whether it's encrypted, and whether all volumes look present, before you try to extract.
Symptom to solution
| Symptom | Likely cause | Go to |
|---|---|---|
| Double-clicking a .rar file does nothing, or opens the wrong program | No extractor installed, or wrong file association | Why won't my RAR file open? |
| "CRC failed" or "checksum error" during extraction | Corrupted or incomplete archive | How to fix a corrupted RAR archive |
| Extraction stops with an error message partway through | Various — disk space, permissions, path length, corruption | RAR extraction error messages explained |
| WinRAR itself won't launch or freezes | Application fault, conflicting shell extension, corrupted install | WinRAR not opening |
| The WinRAR installer fails or won't finish | Blocked installer, permissions, corrupted download | WinRAR installation error |
| A "trial expired" or "evaluation copy" notice appears | Normal reminder — WinRAR keeps working, it's asking you to buy a license | WinRAR expired trial notice |
When the archive itself is the problem
If the file is genuinely damaged, no software can guarantee full recovery — see the honest limits described in how to fix a corrupted RAR archive. If the archive is password-protected and you don't have the password, that's not a bug to troubleshoot; you need the correct password from whoever created the archive.

Frequently asked questions
My RAR file won't open at all. Where do I start?
Confirm you have an extractor installed, then check [why won't my RAR file open](/rar-file-not-opening) for an ordered diagnosis covering software, associations, downloads, and corruption.
Can a corrupted RAR file always be fixed?
Not always. WinRAR's repair function can often fix header damage or recover some data, but severe corruption — especially in the compressed data itself — may not be recoverable. See [corrupted RAR file](/corrupted-rar-file).
Is a WinRAR trial notice a sign something is broken?
No. It means WinRAR is unlicensed but still fully functional, since WinRAR is an unlimited-time evaluation. See [WinRAR expired trial](/winrar-expired-trial).
Where can I check an archive's contents before troubleshooting further?
The [archive inspector](/tools/archive-inspector) reads the archive header in your browser and can confirm format, entries, and encryption without uploading the file.
