Hello,  
I’ve been searching at B&R pages for SD version 4.2.5.4 but it seems is not available anymore. Is still possible to get it somewhere?  
Thank you for answers, Matjaz

Hi,  
does [this post](https://community.br-automation.com/t/safedesigner-version-4-3-1-4/1949/2) answer your question?  
4.2.6.2 should be the recommended version for your case.

I have this version (4.2.6.2) installed, but I need to make changes at the existing application and would like to avoid to rebuild safety application and machine restart. It is quite complicated machine (5-axis CNC) and I am working remotely…
