All my applications deleted!!

I just installed the latest Nik collection update. I clicked the installer. A few windows later got a messsge that I needed to uninstall the previous version with the uninstalled. Did that. Ran the installer again. And ./.

All my applications, apart from the pre-installed ones, had been deleted!!

Luckily I had a very recent backup, but I will be very cautious with DxO updates in future!!

Installing the latest version of Nik, by default it overwrite the last installed version, no need for you to remove them. Unless they change that parameter in V4.

Yes I know the feeling DXO seem to have adopted a scorch earth policy trying to get everyone to adopt the new stuff
