Problem solved.

After raising a tech support request with Siemens and being sent PC_IDENTIFIER (basically a stand alone installation & detection of 'Set PG/PC Interface' control panel applet) I have fixed the issue using the following method:-

• Uninstalled all Siemens applications.
• Deleted all directories called ‘Siemens’ in following folders, including subfolders

C:\Program Files

C:\Program Files (x86)

C:\ProgramData

• Searched through log files to find which CLSID was causing the error, searched through registry and deleted any entries which related to it.
• Also deleted lots of other registry entries with ‘Siemens’ as a search criteria (but not all, used my own judgement & experience to determine which ones).
• Restarted PC and installed only PC_IDENTIFIER software, iinstalled corrctly without error.
• Checked ‘Set PG/PC interface’ in control panel, it is now correctly detecting all interfaces available and SIMATIC Device Drivers WoW now has version 29.01.02
• Installed TIA Portal V13 SP2, interfaces still working.

Would suggest only doing this if you are happy wading around in the registry and I only did this as tech support insisted it was my antivirus (as its not on their 'tested' list)

 Hello, can you share the PC Identifier? I need it, facing same issue
