I am having a similar problem to Tina's.
Not just with the library object icons in Windows Explorer but with the PLN icons as well.
I modify my PLN previews as per that attached imaged which is from the Archicad help file.
I find it useful to keep track of all the file versions with different icons so I can visually see which file was created in which version.
Now the thing is this was working perfectly fine until I installed version 13.
I now just get the default grey page icon for PLNs and the chair for GDL objects (The preview for object in the library browser in Archicad itself are fine).
One good thinh is at least the PLN and BPN icons are a little different now - they used to be the same.
What is worse is I could also hover my mouse over a file in Explorer and it would show a pop-up with the Achicad version it was last saved as.
This doesn't work anymore either - the pop-up shows but without the version info.
Now I have to actually open Achicad and go through the FILE > OPEN menu and select the file to see what version it was saved in.It is a real hassle if you want to keep working on a file in the original version it was created in.
It is not a problem with my system because nothing has been changed.
It obviously stems from the installing of Archicad 13.
File association is to version 13 as you would expect and I don't really want to re-associate them with version 12 (not sure if that would fix the problem anyway).
It has also happened on a second machine as well after installing 13.
Does anyone (Graphisoft?) have an idea of how to put hings back to the way they were?
