Simatic Step 7 V5.5 Service Pack 2 (SP2) is a comprehensive update designed to extend the operating system compatibility and functional capabilities of the classic Siemens PLC engineering suite. Key Features of Step 7 V5.5 SP2

Expanded OS Support: SP2 introduces support for Windows 7 64-bit (Ultimate, Professional, and Enterprise) and Windows Server 2008 R2 (64-bit) with or without SP1.

Enhanced Hardware Configuration: Users can now create I-devices (Intelligent IO devices) from numerous IO controllers and utilize the PROFINET shared device function.

Advanced Networking: Supports dynamic assignment of IP addresses and device names, media redundancy for multiple domains, and isochronous mode for IO devices.

Security & Web Access: Access to CPU web pages via secure HTTPS connections and the ability to manage user rights for the integrated Web server. Simatic Step 7 V5 5 Sp2 Download Fixed

Diagnostic Improvements: New capabilities include setting the CPU to STOP based on specific error classes and evaluating selected Error OBs (Organization Blocks).

Windows Account Control (UAC): Improved operation under Windows 7, allowing the software to run with various UAC notification levels enabled.

Legacy Compatibility: Maintains full upward compatibility, allowing projects created in versions as old as V3.x to be processed in V5.5 SP2 without changes. System Requirements

For stable operation on Windows 7, Siemens recommends at least 2 GB of RAM and a 1 GHz processor. The installation typically requires between 650 MB and 1.2 GB of free hard disk space. # $ + K What's New in STEP 7, Version 5 - Support

Page 1. What's New in STEP 7, Version 5.5? The following subject areas have been updated: Operating systems. • As of STEP 7 V5. 5, STEP 7 V5.7 SP2 Trial Download - ID: 109820861 - Support SIMATIC STEP 7 V5

Post-Installation Checks:

  • Open Step 7 > Help > About. Verify version is V5.5 + SP2.
  • Go to Options > Modify Network Places – Test that the PG/PC interface recognizes your network card (if any).
  • Compile a dummy project to ensure no S7DOS errors appear.

Prerequisites:

  • Clean VM Recommended: Never install legacy Step 7 directly on your daily Windows 10/11 host. Use VMware or VirtualBox with a Windows 7 x64 virtual machine. The “fixed” version might work on host, but a VM guarantees stability.
  • Antivirus OFF: Temporarily disable Windows Defender or third-party AV. The “fix” often modifies registry installers, triggering false positives.
  • Administrator Rights.

Where to Find a Safe, Fixed Download

Most official Siemens partners will direct you to the Siemens Industry Online Support (SIOS). But for a pre-fixed version, consider these legitimate paths:

  1. Siemens Download Manager (Official, but not "Fixed"): You download base V5.5, then SP2 separately. You must manually apply fixes.
  2. Third-Party Automation Forums (MrPLC.com, PLCs.net): Experienced users share "repacked" ISOs that include the registry fixes and prerequisite check bypasses. Always scan these with Windows Defender offline.
  3. Siemens Internal "Update Pack" (for paying SWA customers): If you have a valid Software Update Service contract (SUS), Siemens provides a cumulative DVD image (often called "Step7_V55_SP2_Update.exe") that is effectively the "fixed" version.

1. The "S7KAFAPX.DLL" Crash Fix

When opening some OB blocks (especially OB1 with extensive network comments), Step 7 will crash with a memory access violation.

  • The Fix: Download the hotfix S7KAFAPX_V55SP2_HF3.zip from Siemens support (Article ID: 109478925). Replace the DLL in C:\Program Files\Siemens\Step7\S7BIN. This is the single most effective "fix" for SP2.

What "Fixed" Typically Refers To (Legitimate vs. Illegitimate)

Legitimate "Fixed" Versions (What Siemens should have released):

  • Slipstreamed Installs: An ISO image where SP2 has been integrated with the base V5.5 using Siemens' own "SiSeS" (Siemens Setup Service) tool. This avoids the "rebase" errors.
  • Patch-Integrated Builds: Installers that already include the post-SP2 hotfixes (like HF1, HF3, or the 2018 security patch for CVE-2017-11415).
  • OS Compatibility Mods: Modified setup.ini files that allow installation on Windows 10 or Windows Server 2016/2019 (unsupported but often necessary).

Illegitimate "Fixed" Versions (What to avoid):

  • Cracked EKB (Know-How Protection) Files: These replace the AX NF ZZ dlls to bypass license keys. These are often riddled with malware.
  • Pre-Activated Versions: "Fixed license" files from unknown torrents. These frequently contain keyloggers targeting industrial networks.

Critical Warning: Siemens’ legal team aggressively targets distribution of cracked licenses. However, "fixed" in the context of installation bugs (not licensing) exists in a grey area. Many professional integrators create their own "fixed" master images for rapid deployment. Open Step 7 > Help > About

Common “Fixed” Errors & Troubleshooting:

| Error Message | Why It Happens | The Real Fix | | :--- | :--- | :--- | | "The parameter is incorrect (0x80070057)" | Broken registry path in the “fixed” ISO | Repair using Siemens Registry Cleaner tool. | | "No license found" after applying a crack | The crack is for a different version (V5.5, not SP2) | Re-apply a SP2-specific crack or use a trial license (14 days). | | "MSXML 4.0 installation failed" | Windows 10 lacks legacy MSXML | Download MSXML 4.0 SP3 from Microsoft manually before running Setup. | | "Step 7 crashes when opening Hardware Config" | The “fix” corrupted the HW catalog | Replace the s7hwax folder from a known good V5.5 SP2 image. |

Part 2: The “Download Fixed” Phenomenon – What Does It Actually Mean?

When you search for “Simatic Step 7 V5 5 Sp2 Download Fixed”, you are entering a gray area. The term “Fixed” is not an official Siemens term. In the automation community, “fixed” usually refers to one of three modifications made by users or third-party patchers.

Part 1: Where to Download (Legit & Safe)

Do not download cracked EXEs from random forums. They contain malware or broken registry hooks.

Option A: Official Siemens Support (Requires Login & Contract)

  • Go to Siemens Industry Online Support.
  • Search for "STEP 7 V5.5 SP2".
  • Look for the Download for "STEP 7 Professional 2010".
  • Note: You need a valid service contract or a purchased license key (on USB dongle).

Option B: The "Trial" Workaround (For training/fixing)

  • Siemens sometimes releases a 21-day trial for V5.6. However, for V5.5 SP2, search the Siemens support database for Entry ID: 53704631 (This holds the official update package, but you need a base V5.5 installation).

Option C: Existing Installer (Most common fix)

  • If you have the DVD ISO but it crashes on install, jump to Part 2 below.
