Thank you for your reply. It is very informative but actually answers my next question.
I asked a bit different thing. Not to run 2 wallets on same PC but 2 same wallets on 2 different PCs!?
For instance I have one PC in one city(Boston) and my laptop in another one(Helsinki), but I want to be able to use my DMD wallet in both cities...
If you are talking about the simultaneous launch of two identical wallet (with the same file wallet.dat) then this is possible.
But as soon as you make an outgoing transaction on one of the wallets, then on the second purse, your balance will automatically decrease
