This is a recognizable problem. Since recent updates (late 2025/early 2026), Windows 11 has become a lot stricter with checking programs. This can range from a simple warning to completely blocking an app.
Below are the most common causes and what you can do about them:
If you have these problems within cubase and other DAW software, then the cause is almost certainly in Smart app control
1. Smart App Control (SAC).
This is a relatively new feature in Windows 11 that blocks apps that appear “untrustworthy” (for example, because they do not have a digital signature from the creator).
What to do: If you are sure the program is safe, you can disable SAC.
Go to Settings > Privacy and Security > Windows Security > App and Browser Management > Smart App Control Settings.
Note: Once you disable it, you can often only turn it back on by completely reinstalling Windows.
2. Windows Defender SmartScreen
You get the message, “Microsoft Defender SmartScreen prevented an unknown app from starting.”
What to do: Usually in the notification there is a link to “Learn More.” If you click that, the “Run Anyway” button appears.
Permanent solution: right-click the program file (.exe), choose Properties and at the bottom check the “Unblock” box.
3. Unexpected UAC (user account management) messages.
Since a security update in early 2026, many trusted programs (such as some installers or updates) suddenly ask for administrator privileges when they didn’t before. This is due to a fix for a vulnerability in the “Windows Installer.”
What to do: Make sure Windows is fully up-to-date(Settings > Windows Update). Microsoft recently released “Known Issue Rollbacks” to stop error notifications for known apps.
4. Reports on WinSqlite3.dll or sqlite3.dll
There is a known problem where Windows security wrongly alarms about these files.
What to do: Install the latest Windows updates (specifically those after January 2026). Microsoft has incorporated a fix in this that ignores these “false positive” notifications.
Short checklist for your safety:
Is the message coming from your browser? Beware: some websites show fake “Windows security” pop-ups. Real Windows notifications always come from the taskbar or system center, never from a website.
Has the program been downloaded? To be sure, scan the file on VirusTotal before bypassing security.
Could you tell me what the exact text of the message is? Then I can help you more specifically with the correct setting.
