I installed a stand-alone version of electrum 2.6.4, then deleted it because I thought the seed might be compromised.
why did you think it is compromised?
I then installed the windows installer version, to my dismay the seed was exactly the same!
it is because when you remove Electrum it will only uninstall the program meaning it will remove the installation files not your wallet file. it is located here:
C:\Users\{username}\AppData\Roaming\Electrum\wallets\{walletName}
and this is not removed unless you manually delete it. so after installing another Electrum (windows installer) on the start up it checks that address and since it sees the wallet currently there it opens it up instead of creating a new one for you.
How do I get another electrum wallet with a new seed?
this is already explained by NorrisK
Thanks a lot guys! I did as you said and was able to get a second wallet with new seed.
Thanks
glad your problem was solved.
