I have now successfully registered the program ver 5.1
Uninstalled unregistered version with Revo Uninstaller (available for free)
Then I scanned for leftovers with Revo.
Download the HUB program to my download folder.
Started it as an administrator.
When the program asked if I wanted to install, I clicked “download the installer to the computer” and clicked no for installation.
Then went to my download folder and started the installer as an administrator.
When Sketch Drawer started, I clicked on register and paste the code from the clipboard.
Voila it worked!
