That sounds like the archive might have gotten corrupted during download, or the extraction didn't complete properly.
Try the following:
Re-download the archive — Sometimes downloads get interrupted or corrupted, especially with larger files. Delete what you have and download it fresh.
Check the file size — Compare the size of your downloaded file with what is listed on the resource page. If it's smaller, the download was incomplete.
Use 7-Zip instead of WinRAR — Sometimes WinRAR has issues extracting certain archives. 7-Zip handles them better in many cases. You can grab it free from 7-zip.org.
Extract to a short path — Try extracting to something like C:\RCD instead of a deeply nested folder. Long file paths on Windows can sometimes cause issues with PDF files not being read correctly.
Check your antivirus — Some antivirus programs (especially Windows Defender) can quarantine or corrupt files during extraction. Temporarily disable real-time protection, re-extract, then re-enable it.
If the PDFs are still unreadable after a fresh download and clean extraction, it's possible the files in the archive itself are damaged. In that case, you'd need to wait for the uploader to re-upload a fixed version.
The problem is not solved. I tried again new download. I dont know what happen. The code 2997 amd 2999 didn't work. the app cant read decodes files. I dont know.
That's frustrating, I understand. Let's try to narrow down the problem:
Regarding the PDF/decode files not opening:
What exactly happens when you try to open them? Do you get a specific error message?
What program are you using to open the PDFs? Try Adobe Acrobat Reader if you haven't already.
Right-click one of the PDF files and check the file size — if it shows 0 KB or just a few bytes, the files are definitely corrupted inside the archive itself.
Regarding the wrong codes (2997 / 2999):
Since both codes failed, and the decode files are not working either, it's very likely the tool is not functioning correctly due to the corrupted/unreadable files. The code calculation depends on those reference files — if they can't be read, the output will be garbage.
What I would suggest at this point:
Post your radio details directly in this thread and ask if anyone with a working installation can run the decode for you:
Radio: Skoda Symphony
Part number: 6Y0035156E
sеriаl: SKZAZ9F3780820
Tag or message the original uploader Bin directly — let them know the archive may have corrupted decode files. If multiple users have the same issue, it's likely a problem with the upload itself, not your system.
Hopefully someone with a working copy of v1.9 can generate the correct code for your sеriаl in the meantime. Hang tight.
