Thanks again for trying to help here.
1) I'm not in I.T. so bear with me as I may not use the correct terminology or make sense!
2) I already tried all the compatibility stuff and was thinking the issue might be more to do with where the folder is located. Because I had been able to briefly see something about 'error root exception.'
3) I wanted a way to quickly insert a screenshot. As in screenshot > paste. Rather than having to put the screenshot somewhere, save it, insert it here. Probably a valid reason why screenshots can't be done, but it's easier to do that.
Ok, so I've managed to sort it and thought I would post as this will possibly help others.
The cmd window opening when I click on the app is just a scipt (?) with instructions on where to open the app and the place where the app is, could be wrong. Which is why it says something about the root. So I wondered if it had anything to do with onedrive, having recently discovered that it takes over the desktop. The file that is downloaded from the Norton Password manager page is sent to the desktop, but the desktop is within Onedrive if you have it.
So I deleted the version of the desktop that is in Onedrive and then could not access desktop at all. So went into deleted items and in deleting it from Onedrive it deleted it from the c>user bit too. So I reinstated that one, but left the Onedrive desktop version deleted. Then moved all the Password Manager files into the genuine desktop. And extracted them into the genuine desktop. And then ran the app. And it worked. The cmd box didn't flash open and then close. It paused, was obviously doing something and then all the files appeared.
With the file that is downloaded from Norton, it just downloads automatically into the download folder. Which is fine. But then when you try to open it I was getting error messages and such like because my PC wanted to put it into c>users>myname>onedrive>desktop as opposed to c>users>myname>desktop.
Not a massive fan of MS because nothing ever seems to work well and I have no actual IT experience but their support seems even more clueless than me. Which helps me make decisions about other aspects of remote working for the business and MS365 is probably not going to feature!
Now my actual desktop appears completely empty for some reason because there is no more desktop in the Onedrive. I would have thought that the desktop that I can see (not the file) would be taken directly from c>users>myname>desktop, but it appears that Onedrive has changed that too.
