Any idea what -in the end- cause that rename to fail ? is it in the same realm (somehow) ?
OK, my excuse is that I still feel jet-lagged from coming back from holiday...
I now realise that xxhighend.exe is not being reverted back to the 2.06a version at all. It just so happens that the 2.06a version was dated 12/(can't remember month)/16. The 2.07 version is dated 23/12/16. So when I saw 12/x/x in the date, I thought it was going back to 2.06a. But actually, it says 12/1/17. I never realised xxhighend.exe was 'updated' after each use.
Sorry for any confusion.
