Hello,
I am sorry to say, but I tried all your advices to deal with the connection problem. Nothing is working. I have Windows 10.
Does the wallet work on Windows Vista which I have, if not on Windows 7.
Are you planning a light wallet and also that is can be stored on hardwallet like Nano S Ledger.
Thanks for a reply, Mira
My problem was with a conflicting service running for my Killer Networking brand nic.
Your other problem might be using windows vista but I guess that belongs on another forum (each to their own 
, there is work being done on the wallet backend and light clients which you can read about here
My question was also if I can install it on Windows Vista or only Windows 7, 8 and 10?
10 ist nor working fpr many.
Are you using windows 64 bit?
I do not know where do I see it?
And second, I have also Windows vista where I could intall the wallet, Does it work out?
For windows 10:
To check whether you’re using a 32-bit or 64-bit version of Windows 10, open the Settings app by pressing Windows+I, and then head to System > About. On the right side, look for the “System type”
That should show you 32 or 64 info, It only works on 64-bit.
For vista I cannot answer unfortunately. I haven’t tried myself. If your problems persist you could perhaps try the official support for the wallet:

They have some methods to try and failing that you can send a log file to the team.
