Hello!

I am having a problem with an Win CC 7.5 installation running during several years.

While running suddenly it is not possible to navigate anymore from the last window already open. 

When I open de Graphics Designer the folder with the images Designer  seems empty.

Finally if you close everything and open it again the images appears in the Graphic Designer and after starting the runtime it is possible to navigate again.

Hi Malilo2020,

What operating system does the PC have?

Do you meet the minimum system requirements mentioned in the WinCC 7.5 release note?

The system is running in Windows XP.

This system has been running several years and suddenly the problem i described above has appeared. When you restart the Win CC runtime everything works fine for a while and then it happens again.

Hi again,

I am afraid that Windows XP is not released to work with WinCC 7.5, so there is a high probability of failure and the behavior of the software cannot be predicted.

I understand that the project comes from a WinCC migration, but I consider that the operating system should also be updated to a compatible one, such as Windows 10.

To do this, you can use this Siemens tool:

Compatibility Tool for Automation and Drive Technology

Hello Malilo

does this also happen if you create a new project?

You could also try this:

But of course V7.5 on XP, there is no release
