Is this safe?

Straight answers about who publishes Lotus 1-2-3 Converter, how to install it, and what Windows may show — including Authenticode / code signing by Green 18 Enterprises and the official MSI SHA-256.

Publisher

Lotus 1-2-3 Converter is published by Green 18 Enterprises (Arizona, established 1991).

Conversion runs locally on your Windows PC. Your Lotus spreadsheets are not uploaded to our servers. See also Privacy & Security.

Authenticode / code-signed MSI

The offline Windows installer (LotusConverter-6.2.0.msi) is Authenticode / code-signed by Green 18 Enterprises. Download it from this website (Download the installer), not from third-party mirrors.

Website free trial: 10 conversions.

Verify Digital Signatures

After you download the installer, confirm the signature in Windows:

  1. Right-click LotusConverter-6.2.0.msi → Properties.
  2. Open the Digital Signatures tab.
  3. Select the signature and choose Details (or View Certificate).
  4. Confirm the signer / publisher shows Green 18 Enterprises.

If Windows shows no signature, a different publisher name, or an invalid signature, do not install — contact support@lotusconverter.com and tell us what you see.

Windows SmartScreen

Windows SmartScreen sometimes warns on installers that are new to your PC or that have not built a long reputation with Microsoft's telemetry. That warning means Windows has not built reputation for the file yet — it is not by itself proof the file is malicious. The Lotus Converter MSI from this site is Authenticode-signed by Green 18 Enterprises.

If SmartScreen appears after you download the MSI from lotusconverter.com:

  1. Click More info.
  2. Confirm the publisher shows Green 18 Enterprises when Windows displays a name.
  3. Optionally verify Digital Signatures on the MSI properties (steps above).
  4. If you trust the source, choose Run anyway.

Checksums & VirusTotal

The SHA-256 below matches the official 6.2.0 MSI (LotusConverter-6.2.0.msi). The same hash is published in the WinGet 6.2.0 manifest. Compare it to the file you downloaded; do not rely on hashes from unofficial sites.
