I believe that I have done everything conceivably possible to run SNPPv7_beta. I just managed to get it to run in its most basic form on one laptop but it has adamantly refused to allow any upgrade of the facilities. The downloads are always corrupt - and I have downloaded the 2Gb about 5 times (yes, really), and every one has claimed errors when running. I eventually removed SNPPv7beta from the one laptop to try re-installing in full. That has proved a complete waste of time. I clocked up three days trying to persuade it to install but ever possible error has come up, ranging from 'file extraction error' etc and all of these after waiting 2+ hours for the install!
In the absence of any real help I have now had to carefully remove all traces of SNPPv7_beta from my system. I continue to use SNPPv6 although that crashes on alternate runs!
