So, I changed my C Drive to a SSD Nvme 500Gb because the old drive was full.
Then after updating with Native Access, Traktor 4 failed to work only showing a small white icon with OK on it. and all the other 7 updates failed with "unable to uninstall old program. So I ran the Registry tool. This made no difference.
Now Native Access is totally unusable.
The only time a similar thing like this has happened to me was when I bought the Izotope Ozone 11 & they had two downloaders which didnt work plus iLok & the software didnt work at all.
I notice that Izotope is one of my Native Access Downloads.
