1) When clicking on the original Electrum-2.8.2 downloaded (Standalone Executable) file to install the Electrum wallet, I encounter a screen saying: "This file is encrypted. Enter your password or choose another file." (see djmcg's screenshot above).
2) The first time I used this application file this didn't happen. At all other times the encryption notice did appear.
3) I downloaded a fresh Electrum-2.8.2 Standalone Executable file to a different place on my computer and the same thing happened - I was asked for my password. When I clicked on the [Next] button, not putting my password in the box, a wrong password box popped up and I couldn't go any further (again, see djmcg's screenshot above).
4) I then deleted the Electrum folder in my [Roaming] folder and and the two previously downloaded Electrum Standalone Executables. A fresh Electrum-2.8.2 Standalone Executable file was then downloaded from the
https://electrum.org/#download web page - I had checked several times to make sure it was the genuine Electrum website.
5) I sailed through to the "Confirm Seed" screen, inputted my seed words, and as before the only option available was to go [Back] - [Next] was greyed out. I'm sure I typed in the right words on both installations. When I went back, a new set of seed words was generated. The fresh generated words, as far as I am aware, didn't happen before when I went back. I inputted the new seed words and the [Next] button became active. I clicked on [Next].
6) I proceeded without choosing a password to encrypt my wallet keys and my default wallet (standard) was created. Again there was no shortcut to the wallet on my desktop. The wallet had disappeared. The only Electrum wallet files on my computer were the ones I had before i.e. the electrum-2.8.2 .exe downloaded file and a 4KB default_wallet file in my Wallet folder.
7) The full contents of my [Roaming] file are as follows: Certs (folder); Wallet (folder); blockchain_headers (file); config (file); daemon (file); and recent_servers (file).
This time when I clicked on the
Electrum .exe file, I went straight into the wallet without going through the process I had done before. I then created a password from inside the wallet. As before, I had to go through the
Install Wizard by clicking on the original downloaded
.exe file - see djmcg's screenshot headed
Electrum - Install Wizard.
9) Conclusion: The installation process simply modifies the original downloaded installation .exe file. This file has to be clicked on to activate the wallet and the Install Wizard. I have never experienced this with any other wallet installation - there has always been a separate wallet access icon created on the Desktop.
P.S. the smiley at what should be point eight is unintentional. It seems to have been generated by the number and bracket symbol used in my post and I can't get rid of it!
