+1. Just upgraded this morning and encountered the same issue. It seems to be working as expected, but that warning is extremely troubling, especially since it says "Insecure" on the screen.
Hello.
Any additional info will be helpful for analysis.
At the very least, please let us know the OS and its version, as well as the Portmaster version.
The Portmaster debug info would also be really helpful.
Hitting the exact same issue even after a complete uninstall/reinstall and ensuring assets.zip is deleted. Windows 11 latest cumulative and latest portmaster version (plus). log file shows this line

Windows 11 Home 10.0.22631 Build 22631. Portmaster 2.0.24.
Debug info looks like it might contain some personal info I'd rather not share publicly. Is there a place I can send it to? Should I reinstall before sending to make sure the errors are in the most recent debug messages?
I was able to resolve this issue.
It was SiriusLLM or GPT that was causing the problem, I think... A conflict with Portmaster, I think...
I uninstalled it properly and reinstalled it...
I had this problem afterwards...
but since then everything has been back to normal.
Thank you
I was updated Portmaster with UniGetUI and then, the problem appear.
Any news about this issue?
Install Corruption
Portmaster has detected that one or more of its own files have been corrupted. Please re-install the software. Error: invalid artifact: verify portmaster: sha256sum mismatch
Not yet, unfortunately.
Please confirm that you are using the latest PM version (2.0.25).
Could you please provide the SHA256 hashes of the Portmaster binaries?
To do this, open the Windows Command Prompt (cmd) and run the following command:
for %f in ("C:\Program Files\Portmaster\*") do @certutil -hashfile "%f" SHA256
I’m interested in the command’s output.
Okay, well, I could fix it by backup the config, uninstalling Portmaster, also had to delete all leftover files, reinstall it and restore the config.
Why it was broken is still a mystery.
I'm on Linux:
❯ pacman -Q |g portmaster
portmaster 2.0.0-2
I got the same error:
Running on Windows 11 Pro 24H2, Build 26100.6584. Running Portmaster 2.0.25
I had updated Portmaster with UniGetUI and then the problem appeared.
Same for me. That lets me assume the winget version of Portmaster is broken?

Thanks, I’ll check the hashes tomorrow.
Just FYI: we only support installation methods listed on the official Portmaster website — https://safing.io/download/
We do not support installing the Portmaster app via UniGetUI or WinGet.
Using unofficial or custom installers is at your own risk.

But who put it under Safing.Portmaster name on WinGet (which is used inside UniGetUI). Cause this name would mean that Safing would be the user/organisation who uploaded it afaik...
Edit: Oh welp, it looks like it had been added by a user named @OfficialEsco
microsoft/winget-pkgs@97bc1cf
And under the hood its using https://updates.safing.io/latest/windows_amd64/packages/Portmaster_2.0.25_x64-setup.exe to get it installed:
microsoft/winget-pkgs@e0213bc
But yeah the thing is, I am using UniGetUI to keep everything updated. I had originally installed Portmaster from the website, but UniGetUI thought winget's version would be better and when there was an update in portmaster, it had overridden the official install and just used winget's version.
Hello,
We have identified the issue.
The root cause was a file hash mismatch between the installer and the update repository.
The issue occurs when running the latest installer after the app has already been automatically updated to the latest version using the internal update mechanism.
This problem does not affect any app functionality — it only results in a warning notification.
To suppress the installation corruption warning, you can manually remove the following file and then restart Portmaster: C:\Program Files\Portmaster\index.json
We have updated our internal scripts to prevent such issues in future releases.
Special thanks to @Miniontoby for your support!
