This error code 0xc0e90002 indicates that Windows Memory Integrity (part of Core isolation) is blocking the JusPrin DLL from loading. This is a Windows 11 security feature that validates code integrity at runtime.

To confirm this is the root cause, please try the following:

1. Open Windows Security → Device security → Core isolation
2. Turn OFF Memory integrity
3. Restart Windows
4. Try running JusPrin again

Expected result: If JusPrin starts normally after disabling Memory integrity, we've confirmed the issue is HVCI compatibility.

Important: Please re-enable Memory integrity after testing, as it provides important security protection.

---

If this resolves the issue, we'll need to rebuild JusPrin with HVCI-compatible compiler flags. The error is specifically happening with itself, suggesting the DLL doesn't meet the code integrity requirements enforced when Memory Integrity is enabled.

Can you test this and let us know the results? This will help us determine the next steps for a permanent fix.

Your suggestion are rights. I must be also disable "smart app check" (I'm not sure of translation in english version so I attached the screenshot) for resolve the issue. After reactivation of Memory integrity the app continue to start. But the "smart app check" is unable to reactivate (now the option is gray).

Thanks for your support.

PS: the portable windows asset is a zip with inside the zip with same name , so must be extracted twice! And first extraction must be do in another folder for not do a issue (for the same name)
