Only for files downloaded from www.mailqry.com: right-click the MSI → Properties → Digital Signatures → select Setec Informatica s.r.l.s. → Details. Check that the signature is valid before continuing.
With a valid signature: Properties → General → Unblock (if shown) → Apply → OK. Then open the MSI again. This removes the Internet mark from this file only.
SmartScreen may still warn about a signed file. Only for an unrecognized-app warning, after the checks above, choose More info → Run anyway if available. For malware alerts, an invalid signature or an organization block, stop and contact support or your IT administrator. Do not disable antivirus or SmartScreen.
