I had the same trouble with SoMachine (Schneider) but guess this could work for you:
For people that might have the same problem (sorry, can't write German) but this is a setting in SoMachine that will allow yuo to use this latest version of OSCAT library.
The reason is that the name is in conflict with another (standard) library.
The procedure to resolve this problem:
* start SoMachine and choose to open Library File
* search for the installed OSCAT library and open de library
* under the "Program" tab you select the POU view
* open the "Library Manager" in the explorer window
* right Click on the OSCAT library in the window on the right and choose for "Properties"
* a new window opens and select "Newest version Always"
* click on "Save Project And Install In Library Repository" (the symbol next to the "normal" save symbol
This will do the trick. The person that had this problem for sure has already resolved this problem but hope this solution helps others.
