This is usually caused by:
- The antivirus, which is STILL blocking them, even if you excluded them
- You might inadvertently un-trusted "Virtuali" on your system so, anything signed by us will be automatically refused to run.
To verify this, you can go to the Control Panel, under "Internet Options", look for the "Content" tab, there should be an "Authors" button, that will list the software authors that you trusted, and another tab with untrusted authors. If you see "Virtuali s.a.s", remove it from both tabs (especially if it's under untrusted)
