My copy of Ad-Aware 2007 plus is now working properly and it registered first go! I didn't update first, it didn't seem to need it?
I was asked for a hardware finger print key, I assumed they meant the one from my broken machine. I did manage to extract it from the old hard drive with a bit of difficulty. As it turned out Lavasoft wanted the new machine finger print and all was well.
I thought it strange at the time, supposing the drive had died and there was no way to find that code number?
Perhaps it's me being stupid, or Lavasoft should state it's the new number that's required. The confusing thing with that is, you have to load Ad-Aware first to get the number, then remove it as and then re install it as instructed.
Well that one is solved, now all I have to do is find out why my wife's machine won't load Ad watch when started. It did register OK and did work fine for a while, now I have to manually start Ad watch every time it's booted. (Yes, it does have a separate licence).
