For me it was different ... I‘m on mac OS ... don‘t know if that might play any role.
When I installed Pigmets‘ demo it didn‘t show as a demo in ASC, but as a full version. When I started it, it showed the demo „x days left“ notification.
Then when I bought it bundled with V Collection, the next strange thing happened ...on the invoice I saw only VC, no word about Pigments. But when I recieved my mail with the serial numer, I had a second one for Pigments.
Nothing else changed, except that the „x days left“ vanished after starting Pigments again. So I didn‘t reinstall and saw no changes in ASC ...Pigments is listed there as before. It‘s also listed as registered under „My Products“ on the website now.
