1. I downloaded setup file from this website and Alpari UK;
2. Install them on Windows 7
3. Cant register new demo account when the client is installed under Windows 7 (It's working fine under XP)
4. Have disable UAC and firewall on Windows 7, but the issue can be solved.
5. Tried run MT5 client with admin user, the issue still existed
6. Tried run the MT5 client with "/portable", still no lucky.
Can any guys give me some advice on this ? Thanks you very much in advance.

Sorry for wrong message, I have updated it. The issue can't be solved by disabling UAC and firewall on Windows 7.

A OK. Don't know then. Friends of mine has MT5 on 7 with no problem, so we clueless about this. Use Google advance search, and search win 7 - and also search for Win Vista - though that may not helps - on each MQL5 and MQL4.com. :(
Do you mean "register" or "login"?
If you mean "register", are you sure that the problem isn't simply that you are trying to re-register details for a demo account which you have previously registered?
It may not be an issue specific to win 7. It may just be that you tried to register the win 7 MT5 account AFTER the XP attempt - and the problem might have been reversed if you had attempted them in the opposite order.
Brokers in general (including Alpari in particular) do seem to have a tendency to arbitrarily delete/invalidate demo accounts - especially if you try and register multiple demo accounts with the same details. Try varying the registration details.

Both MT4 and MT5 are working on Windows 7 now, I didn't do anything. Just sent two file which were captured by Wireshark to Alpari. That's all.
Many thanks you guys for your great help....
