7zip@25.01: decompress error

[DCiprut]

Hereby the console log under PS 7 Admin with RemoteSigned Execution Policy :

PS C:\Windows\System32> Get-ExecutionPolicy -list

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined

PS C:\Windows\System32> scoop install 7zip -g
Installing '7zip' (25.01) [64bit] from 'main' bucket

Please try again or create a new issue by using the following link and paste your console output:
https://github.com/ScoopInstaller/Main/issues/new?title=7zip%4025.01%3a+decompress+error

Retrying and emptying %temp% folder did not change anything. No log found around however.
The subject MSI File can be duely opened and viewed under Explorer, WinRar or 7z. However trying to install it thru double click leads invariably to Windows Installer Error Message : Unable to open the installation file. Invalid Windows Installer package.

Please note scoop has been successfully installed but with User Scope in spite of running the GitHub downloaded Install-ScoopForAll.ps1 script under PS 7 with administrator privilege (after failing to install as Admin according to https://github.com/ScoopInstaller/Install#readme recommendations).

Thanks in advance for help. I would like to install scoop globally and thought (since 7z and Git are prereqs for scoop install) I should first install 7zip under global scope berfore uninstalling the User Scope version like I successfully did for Git, but this proves unfeasible up to now, giving this msi error.

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

• 7zip package decompression/extraction error
  Make sure you have the latest version of 7zip installed:

  scoop update 7zip
  

  If you have enabled use_external_7zip, update it using the appropriate method for your setup.

• MSI package decompression/extraction error

  • If you are using default MSI extractor (msiexec):
    This is usually caused by a msiexec process exception, try one of them:

    • Switch to alternative MSI extractor then retry: scoop config use_lessmsi true (Default: false).
    • Resolve the msiexec exception/occupation then retry, if you know about it.
    • Restart the PC then retry.

  • If you are using alternative MSI extractor (lessmsi):

    • Switch to default MSI extractor then retry: scoop config use_lessmsi false (Default: false).

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.

Hello, nice suggestions.
I'll keep you informed when I will find time to try those out. In the mean time I'll stick with the current state of affairs namely :

PS C:\Windows\System32> scoop list
Installed apps:

7zip 25.01 main 2025-12-20 23:42:24
7zip 2025-12-21 10:58:30 Global install, Install failed
ack 3.9.0 main 2025-12-21 09:58:21 Global install
git 2.52.0 main 2025-12-21 10:01:19 Global install
perl 5.42.0.1 main 2025-12-21 09:46:57 Global install

with my User Scope scoop install. Some more info about my wish to go for a global scoop install. I had success to install git globally then uninstall it's user scope version, but failed to do the same with 7zip.

Until then I wish merry Christmas and Happy new year to all.
