Project is starting in Simatic RT Start and I can both start and stop it from it.

Problem with starting Graphics runtime. Nothing shows just WinCC icon and message ""no connection to the script control".

Additionaly when I try to run Reset_WinCC.vbs from windows menu "There is no file extension in "C:\Program" Windows script host appears. It works fine if I try to run it from powershell after changing directory to WinCC bin folder.

Project was running fine until half of december

Thank You for your attention

Hi Agomirr

In relation to the first issue, you can try the following:

• Delete the DCF file of the project as described in this FAQ: Update the configuration file of the WinCC project (delete DCF)
  
• Check if there is enough memory available on the hard disk. You might find useful this FAQ: Why does the SIMATIC WinCC Runtime not start up or hang in the Start routine?

On the other hand, the error  "There is no file extension in 'C:\Program" it might be caused by a wrong path. Does the path contain spaces or special symbols in its name? 

Good luck! 

Hello I've already tried deleting the dcf files and it didn't help.

The disk has more than enough free space on it - almost 1 TB of free space

And yes the "program" invalid path might be caused by the spacing error but it is a path to "program files (x86)" which is always named with spaces and it works on different computers.

Any ideas on why it causes problems in this specific setup?
