I am using wincc 7.5 sp2 with update 12 but my tag management closed shortly after opening .

Hi kratul,

In order to have some more information I would like to ask you the following questions:

- Is this only happening with a specific project or with all of them, could you test with a very simple project and see if this happens to you?

- Do you have other software installed on the PC where it is installed, such as WinCC Professional or Unified?

- What version of Windows do you have installed? It would be helpful if you could attach a screenshot of the exact version from the 'Winver' command.

I look forward to your answer and best regards!
