Hi all, I found that problem is in service:  "S7DOS Help Service".

1. Check if this service exist and if it is running on your PC.

2. If  the service does not exist do following:

a) check if this file exist on your PC:

Program Files\Common Files\Siemens\Automation\SimaticOAM\bin\s7oiehsx64.exe

b) make the service by "sc" command (run command line as administrator):

sc.exe create "S7DOS Help Service" binPath= "C:\Program Files\Common Files\Siemens\Automation\Simatic OAM\bin\s7oiehsx64.exe"

c) run the service and change the start up  mode to automatic.

This only help me to solve the problem with "empty PG/PC interface"

I have allways the same Problem with PST4.2.0.1 under Windows10 Pro 64bit. The interface list will not open, I have tried all indications above, without success. Who can help me?

the Proneta works also with S7-300 components?

My friend, try to use control panel to Set PG/PC Interface.

SilaKg,

This solution works. Watch out for Win 10 v 1903. I am finding many issues with it.
