Absolutely, a long winded pain.
I purchased Version 4.0 a couple of years back on disc.
Yesterday I copied all three discs onto memory card that I used to install it on the notebook that I keep in the 8. I had not realised before but it included an update to Version 4.1. The Notebook is on Windows 10 Home and I did not need anything like Adobe SVG, Win 10 already had something in it to cover.
It is running well.
I notice on Fleebay that some of the posts claim that Version 5.3 includes a "Parts Catalogue", and some of the pictures show that the circuit diagrams are coloured. Can you possibly confirm these points?
One of the advertisers claims that his is actually Version 4.0 but includes updates to 4.1, 5.0, 5.1, 5.2 and 5.3. His is on three discs. Others are downloadable but do offer full assistance in installing. Doing the basic install to 4.0 and then going through all the individual updates could be possibly time consuming.
Another point is that on my Version 4.0 documents it states that "it must be loaded to and run on the OP system hard drive". My built-in "C" drive is relatively small, and I would prefer to operate ElsaWin from my 128GB "D" drive. I do this all the time with my desktop (i.e. keep all my programmes separate from my OS) and do not see any reason why they insist on using the "C" drive. Unless it is make it easier for the novice to load correctly.
