Hi again Dom,
The following account might be a bit hard to follow but here goes anyway...
After all the additional work you had kindly gone to in creating another version of nbsc in order to help track down the problems it seemed only fair that I put some additional effort into getting it running here.
I know many people have installed the .net framework and had few if any problems but to be honest that has not been my experience in the past though I may have just have been unlucky? Working on the theory that perhaps the fault is with the .net installation process I decided to look into this further.
I collected together all my Windows based laptops (dont ask) of which only 4 have Win 7 installed. Of those, two of them are physicaly identical and had been purchased at the same time and from the same dealership so I knew the history and use of those machines. The parameters of the two machines are the same as those I quoted in an earlier posting.
Both machines have Win7 but the one I had been using to test nbsc had a fairly recent re-installation of the OEM Win7 supplied on its internal h/disk. The second identical machine I am now testing has Win7 still running from the factory installation done many years ago and has had many installations and removals of software and files. Oddly enough this second machine with a history of intense use and no maintenance has remained very stable and upon installation of your most recent version of nbsc software it worked!
So now I can look forward to reading the extensive write-up from your webpages on the operation and use of nbsc
http://authorityfile.co.uk/NBSC/articles/software.aspxIts still something of a mystery as to the issues I am seeing but at least I have one machine now able to run the software
As an aside, I also attempted to install nbsc on a third machine. The third machine is my "Sunday best" laptop (Acer Aspire) which has had little use and a recent re-installation of the OEM Win7 operating system. In common with the other problem laptops it appears to run other software reliant on the .net framework but not nbsc. The one thing both problematic laptops have in common is the re-installation of the OEM Win7 operating system.
So, we have some distinct progress and (hopefully) some avenues of exploration. I have one more laptop with Win7 installed and just like the one successfully running nbsc it has an original and unmaintained Win7 installation so it will be interesting to see what happens when I put nbsc on that one
I will let you know what happens.
One last thing, I attempted to install nbsc on a newer, higher spec laptop running Win8.1 but it informed me that "the installation package was not valid" or something to that effect. Would you expect that to happen for Win8.1 ?
I suspect this posting will raise more questions than answers but its nice to be able to report positive progress and I look forward to running the simulation and feeding the output into a modulator for future magnetic recording experiments.
