Decompression/extraction errors can be caused by various reasons. Here are some common solutions you can try:

• Inno Setup package decompression/extraction error
  Make sure you have the latest version of innounp or innounp-unicode installed:

  scoop update innounp -f
  

  scoop update innounp-unicode -f
  

Note

Innounp was previously incorrectly updated to version 2025. Since this version number is higher than the actual latest version, it prevents automatic updates. If you are on this version, please run scoop update innounp -f.

Important

Sometimes, the latest version of innounp may not support unpacking the latest Inno Setup packages.
You might need to wait for an upstream update of innounp.
See: https://github.com/jrathlev/InnoUnpacker-Windows-GUI?tab=readme-ov-file#inspect-and-unpack-innosetup-archives

If none of the above solutions work, it may be caused by other reasons like:

• Extraction blocked by antivirus.
• Extraction failed due to insufficient disk space.
• Extraction method outdated due to changes in upstream package type or structure. May need a manual fix for manifest.
• ...

If the problem persists, please keep this issue open and paste the log content from the failed installation, if available.
This will help us diagnose and resolve the issue more effectively.

Warning

If you are using an unofficial Scoop-Core with an official bucket,
the decompress error may be caused by significant differences between the official and unofficial cores.
In this case, please try switching to the official Scoop-Core instead.
