Hi, 

I have Step7 v5.7 installed on Windows 11.

I need to open a project with safety blocks. It gives me the following message:

"The block can only be read because the software package "S7 Distributed Safety" required for fail-safe programming was not found on your computer"

I tried installing Simatic_DSafety_V5_4_SP5_UPD2 but it gives the following message:

"The wizard was interrupted before S7 Distributed Safety Programming could be completely installed"

I tried to run the installation on a Windows 10 PC for test and it worked without problems. I am able to open the FB-s.

Now, I can only use the Windows 11 PC for developing so I would need and appreciate any help on this topic.

I tried running the installer in different compatibility modes, but without success.

Thank you,

Robert.

Hi,

the error message and remedy is described here:

Why is the installation of S7 Distributed Safety V5.4 aborted in Windows 7 / Windows 10 Enterprise/Professional 64-bit?

Maybe it works also on systems with Windows 11, its worth a try.

Thank you for directing me towards this solution.

I can confirm IT WORKS on Windows 11 as well.

Have a nice day!
