Straight answers about who publishes Ami Pro Converter, what the installer is, and how conversion stays on your PC.
Ami Pro Converter is published by Green 18 Enterprises, an Arizona software studio established in 1991.
Product site: https://amiproconverter.com
Parent company: https://green18enterprises.com
The official Windows installer is an MSI file: AmiProConverter-6.3.0.msi (current version 6.3.0).
Download the official MSI from this website only. Treat any other copy of the installer as untrusted.
The website trial covers up to 10 file conversions. Conversion runs locally on your Windows PC; your .sam documents are not uploaded for conversion.
The offline MSI is Authenticode / code-signed by Green 18 Enterprises. Before installing, confirm Windows shows that publisher on the signed installer.
Right-click AmiProConverter-6.3.0.msi → Properties → Digital Signatures, then open the signature details and confirm the signer is Green 18 Enterprises.
Only download the installer from https://amiproconverter.com — not from mirrored or third-party sites you do not trust.
New or less-downloaded desktop installers often trigger Microsoft Defender SmartScreen — even when the MSI is Authenticode-signed by Green 18 Enterprises. That warning means Windows has not built reputation for the file yet — it is not by itself a malware verdict.
If you downloaded the signed MSI from this site and you are comfortable proceeding: choose More info, then Run anyway. Confirm the publisher shown is Green 18 Enterprises.
