Nothing is ever simple, is it ?
I purchased the 1851 and 1881 British censuses, and found that I needed the resource file viewer, that was in the 1881 wallet, but then found I would also need an additional CD, at more expense of course.
In disgust I shelved those CDs, feeling that I had made a purchase in good faith, expecting it to work.
Now, modern computers do not have CD drives, so the only way is to load the entire file onto the hard drive of an old system, then transfer it to the new one.
I do not use Windows, I have a Mac. I did e-mail the LDS, but they were not at all helpful, stating that they no longer support that system.
So I am left trying to find some way to make use of what I have.
