I reached the end of my rope on this one.

We have installed Solidworks (2015 sp05) and Draftsight (2015 sp3) on Windows 10 (build 1803).

But we cant change the extention association of dwg and dxf files to open in Draftsight. It always opens in eDrawings.

Now we have found a way to solve this issue, by changing the association in the registry, so the files open in Draftsight.

Only the files in the vault dont change their icon. It still looks as eDrawing, but is opened with Draftsight.

How to solve this?
