If you see something like this when installing DRE, this is a false-positive for the Windows Defender Antivirus.

The reason why DRE gets these flags, I believe, is its nature of logging user-defined key-presses to send forward to the sim. A lot of viruses use keylogging for malicious purposes, and understandably it’s difficult for virus scanners to tell them apart.

To clear the DRE installer, do the following:

1. Open Windows Update by searching for Updates in Windows Start Menu
2. Click the Check for updates
3. Windows will now download the latest Anti-virus info which should clear the DRE installer
4. You can now try install DRE again
5. If the app is still marked as a threat, delete the DRE installer, and download it again and retry
6. Finally, try whitelisting DRE in Windows Defender: Approve the app in the protection history of windows defender

Disable Smart App Control

Smart App Control is a Windows 11 security feature that can block apps it does not yet trust, even when the app is safe. If DRE is being stopped by Smart App Control, turning it off can let the installer and app run normally.

Should I disable Smart App Control?

To disable it:

1. Open Settings
2. Go to Privacy & security
3. Open Windows Security
4. Click App & browser control
5. Open Smart App Control settings
6. Select Off

If you cannot change the setting, see this video.

If you do not see Smart App Control on your PC, then it is either already off, not available on your Windows installation, or your device is not using that feature. In that case, continue with the antivirus definition update steps below.

Ensure you have the latest antivirus definitions

1. Open Windows Defender in your applications list, or go to Settings > Update & security > Windows Defender > Open Windows Defender Security Center. Click on Virus & threat protection.
   1. 
2. Click on Protection updates
   1. 
3. Click Check for updates
   1. 

Usually clearing the DRE installer takes 4-8 hours from upload, and Microsoft usually quickly “flushes” the outdated anti-virus information on your machine, so if it doesn’t work immediately, try a restart or wait a day.
