Part 2: The Challenge of Downloading DIGSI 4.95

If you search for "Siemens Digsi 4.95 Download," you will encounter a minefield. Here is the truth:

Siemens does not offer DIGSI 4.95 as a public, free download.

Unlike open-source software, DIGSI is a proprietary commercial product. Siemens has retired DIGSI 4 from active sales and support. As of 2023-2025, Siemens’ primary download portal (the Industry Online Support or the Software Update Service) has removed DIGSI 4.95 from the “Public” section.

Option A: Existing Service Contract (Software Update Service – SUS)

If your company purchased a SUS agreement for DIGSI 4 before its discontinuation, you can still access the download via the Siemens Industry Online Support (SIOS).

  1. Go to support.industry.siemens.com.
  2. Log in with your company’s registered account.
  3. Navigate to “My Licenses” or “Software Downloads”.
  4. Filter by “DIGSI 4” – version 4.95 should appear if your contract is active.

"No valid license found"

  • Cause: The USB stick is not inserted, or the license is for an older version (e.g., V4.80).
  • Fix: Insert the stick. If the version is old, right-click the license in ALM and check if an upgrade is permissible (requires internet connection to Siemens server).
