Hi,

I found this post: Missing PG/PC interfaces on Windows 10 - 210351 - Industry Support Siemens

tried to solve issue on my PG but it didn't work.

Missing interfaces, anytime I start working with TIA (v16 mostly) the interfaces are missing, only TeleSync stays in the list. So far only temporary solution for me is to run (admin) the "s7oiehsx64.exe" file. Then my interfaces are coming back to life.

The reason of why it\s missing I'm not sure, but it might got something to do with using "CCLeaner" with deep analysis and cleaning also some broken registry keys. But as I wrote, I'm not sure of it. No update of Windows, or TIA in that time happen, so it's not that.

I tried to find the missing registry key, but it is different then described above; it is few years later, so perhaps it changed as well. If anyone could help me with it, I apprecciate really. 

Added one line (marked in yellow on attachement) - please correct me if it's wrong. I search the "path" within "siemens" folders in registry to find it.

kind regards

Mariusz

Split from Missing PG/PC interfaces on Windows 10.

I did this change in Services and will test it in few minutes on the machine; if I will see all interfaces that were normally installed and configured

yes, that seems to work :)

it's a good solution - hope others will find it usefull as well

thank you very much for your help!
