Description

Windows Defender may block the installation of Statistica with the following message:

 

Windows Security
Part of this app has been blocked
Some features of Windows host process (Rundll32)
may not work because we can't confirm who
published CustomActions Project.dll that the app tried
to load.

Environment

How to Turn Smart App Control Back On

 

Step 5: Re-enable Protection

  1. Return to Windows Security > App & browser control > Smart App Control settings.

  2. Switch the option back to On (or Evaluation if preferred).

 

 

Alternative Option: Disabling SmartScreen / Reputation-Based Protection (If SAC is locked)

If Smart App Control is greyed out or unavailable on the user's PC, you may only need to temporarily toggle Reputation-based protection:

  1. Go to App & browser control > Reputation-based protection settings.

  2. Temporarily turn off Check apps and files or Block potentially unwanted apps.

  3. Perform the installation, then switch the toggles back On.
