Comprehensive Guide to Completely Uninstalling and Reinstalling Siemens TIA Portal: From Residual Cleanup to System Stability Restoration

1. Introduction & Scope

Siemens TIA Portal (V13–V19) leaves deep system traces during installation, including MSI product codes, Windows services, and drivers. Incomplete uninstallation causes version conflicts, GUID errors, and hardware issues (e.g., Code 19/45 for keyboards). This guide provides a fully automated, step-by-step solution to resolve these issues, covering:

• Deep component removal (programs, drivers, services, registry)
• Hardware error repair (Upper/Lower Filters)
• Pre/post-installation checks (media validation, license recovery)
• System health restoration (DISM/SFC/BCDEdit)
• Rollback scripts and error lookup tables

2. Pre-Uninstallation Preparation

2.1 Backup Critical Data

• Projects: Archive via TIA Portal’s “Archive” function (.zap13/14 files).
• Licenses: Export via Siemens Automation License Manager (ALM) to USB.

2.2 Tool List

Tool	Purpose	Source
TIA Administrator	Uninstall same-version packages	TIA installation media
CleanUpTool	Official deep-clean script	Siemens FAQ #109482460
Revo Uninstaller	Advanced residual scanning	revouninstaller.com
PnPUtil/DevManView	Remove orphaned drivers	Windows ADK

3. Official Uninstallation Tools

3.1 TIA Administrator

1. Open Siemens.TiaAdmin.msi from installation media.
2. Filter “Installed” packages → Select TIA Portal version → Uninstall → Reboot.

3.2 CleanUpTool

1. Download CleanUp_TIA_Vxx.exe from Siemens FAQ.
2. Run as admin → Select target version → Reboot after completion.

4. PowerShell Script for Batch Uninstallation

powershell# C:\Cleanup_TIA_All.ps1$patterns = '*Totally Integrated Automation Portal*', '*SIMATIC*', '*TIA Admin*', '*PLCSIM*', '*WinCC*'$regPaths = 'HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall', 'HKLM:\SOFTWARE\WOW6432Node\...\Uninstall' $apps = foreach ($path in $regPaths) {  Get-ChildItem $path | ForEach-Object {    $displayName = (Get-ItemProperty $_.PSPath).DisplayName    if ($displayName -like $patterns) { $_ }  }} $apps | ForEach-Object {  Start-Process msiexec.exe -ArgumentList "/x $($_.PSChildName) /qn /norestart" -Wait}

Execution:

powershellSet-ExecutionPolicy Bypass -Scope Process -Force& C:\Cleanup_TIA_All.ps1

Reboot required after script completion.

5. Graphical Tools (Revo/Uninstall Tool)

• Revo Uninstaller:
  1. “Forced Uninstall” → Search “Totally Integrated Automation” → Delete all residues.
• Uninstall Tool:
  1. “Batch Mode” → Select Siemens software → “Deep Clean”.

6. Cleanup Legacy Drivers/Services/Registry

6.1 Remove Siemens Services

batchsc query type= service | findstr /I "Siemens SIMATIC TIA" > svc.txtfor /f %%s in (svc.txt) do (  sc stop %%s  sc delete %%s)

6.2 Fix Code 19/45 Keyboard Errors

1. Open regedit → Navigate to:HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}
2. Delete UpperFilters/LowerFilters → Create a new multi-string value UpperFilters with kbdclass.

6.3 Remove Zombie Drivers

batchpnputil /enum-devices /problem > zombie.txtfor /f "skip=2 tokens=1,*" %%i in ('find "Problem" ^< zombie.txt') do (  pnputil /remove-device %%i /subtree /reboot)

7. System Health Check

batchdism /online /cleanup-image /restorehealth  # Repair component storesfc /scannow                                # Validate system filesbcdedit /enum {current}                     # Check for safeboot flags

To revert safeboot:

batchbcdedit /deletevalue {default} safebootbcdedit /deletevalue {default} safebootalternateshell

8. Reinstallation Guide

8.1 Media Validation

• Verify ISO integrity via SHA-256 checksum or use Siemens MediaCreator.

8.2 Silent Installation

batchStart.exe /isolog:"C:\TIAinstall.log" /silent

Check C:\ProgramData\Siemens\Automation\Logs\Setup.log for errors.

8.3 Reboot Nodes

Step	Reboot Required?	Notes
After CleanUpTool	✅	Free locked DLLs
Post-PowerShell script	✅	Windows Installer requirement
After STEP 7/WinCC/PLCSIM	✅	Register drivers

9. Troubleshooting Guide

Issue	Root Cause	Fix
“Detected older version”	Residual GUIDs	Run PowerShell script
Keyboard Code 19/45	Corrupted filters	Rebuild UpperFilters
OPC UA Service failure	Lingering trace services	Delete services + reinstall
CleanUpTool “reboot required”	Pending uninstalls	Restart

10. Automation & Best Practices

• Package scripts (PowerShell, service cleanup, .reg fixes) into a Git repo.
• Deploy via MDT/Intune for enterprise automation.
• Reduce reinstall time from 4 hours to 30 minutes.

Final Note: This guide synthesizes official documentation, field testing, and community fixes to eliminate TIA Portal reinstallation headaches. Always test scripts in a non-production environment first!
