Thank You BB for your comprehensive reply - very helpful.
It was, as you described, the Licence Management System called C_DILLA planted silently on my PC without any banners or warnings during the Autorun phase of the CD spin-up
before the install options screen was displayed. Had I aborted the installation, the intrusive folder/files would have remained; they remained even after I had installed and uninstalled the offending program. I had to delete the rubbish manually from the HD and also from the Registry.
I did a test copy of the CD while the Program was installed and the C_DILLA stuff was still there; no problems.
The irony of this? This illegal (in my view) planting of this software on my CD without my knowledge or approval was done by the UK's leading Consumer Rights Activists called the Consumers' Association on their 1998 Income Tax Calculator called Taxcalc 98!! If I'd realised this before, I'd have asked for my money back. They've stopped doing it on later years' CDs! <img src="mad.gif" border="0"> <img src="mad.gif" border="0">
