Problem solved
- I created four empty folders under C:\Program Files\NewTech Infosystems\NTI CD & DVD-Maker 7\ (Default, JCMDefault, WEDefault, DFDefault)
- There was no copy of ResLiveUpdtEN.dll, instead there was a Dutch version ResLiveUpdtDU.dll. I made a copy of this file, renamed it to ResLiveUpdtEN.dll and placed it beside the Dutch version in the appropriate folder.
Thank you all, and a Happy New Year
