Long explanation - please read.
I am playing a couple of games using HPS NRC without a problem. Except in the actual result of the contest

I am trying to play Michel Paoli, he has V 1.07 rather than V 1.06.
He sent me the zip file for 1.07 which Windows (W 7) refuses to open because it may be harmful !

I am trying to get the original - FM Moss has the info.
B U T !!
As Michel has pointed out he cannot go back to V 1.06 as he is in the middle of a couple of other games.
This made me realise that I am in middle of a couple of games also. My game is in a folder "HPS Napoleons Russian Campaign". If I ever get to be able to unzip 1.07 could I create a folder "HPS Napoleons Russian Campaign 2", install the game, then upgrade that folder?
Back in the days of DOS it would be simple but programs put things in the Registry etc so not all parts are in the game folder. Could/Would this cause conflicts?
Given that Matrix can play the old John Tiller - did not think the version would make a difference?
For those that have read this far - I created the game and did my turn, sent it to Michel who was able to play his turn. But when the file came back to me it let me enter my password and asked me if I wanted to see the replay - then presented me with a single hex.
