I'm getting there - I've now found the loader file and have run it - it doesn't seem to see the application software - that I have now uninstalled and re-installed - when re-installing the installation package ended with the option to open the Application Loader - I did this yet it still didn't find the software! All the option boxes etc are greyed out so there is no obvious way of going to look for it and where will it be anyway?
And to think, 286's and 386's were so easy...
