This was pretty much a waste of time - the person I'm helping either forgot about their BTC ownership status or used also a different app/website for bitcoins.

Because booting into Hiren's is exactly what I did earlier today, then it was much simpler to find the wallet folder with just explorer. It was Users/<user>/.electrum/wallets which was probably the default installation path for that version on Windows. I copied the wallet file and pasted it into wallets directory on my laptop. But the account was once again empty - it is most likely just the 13 word seed account I got into earlier. Unless simply copying and opening it is not sufficient?

Anyways, thanks everyone for help so far, here's probably my last question - any clue which other app/website was popular when Electrum 2.6.3 was used (around March 2016 or a bit later from what I see) and could have been chosen by a not really technical person? The 12 word combination may be the seed for it. Unfortunately I didn't see any other obvious bitcoin app in Program Files, so probably a website? Or it could be just all imagination. Hopefully not.

Ok, so the person I'm trying to help apparently had multiple addresses because I found other 13 word combination and that worked after figuring out one ugly typing of a word. But after entering a new password it was empty and had not even a single receiving address, which likely can't be the proper one because I'm certain that person used a non-expiring address at one point. And he also claims to have around 1 BTC on it. So for now I'm assuming it's true and there's another word combination I just can't find in hardly readable notes. Maybe 1 word is missing from the 12 word one I was talking about earlier.

So I think I'd rather go the files way. But even looking for hidden directiories there was no AppData/Roaming/Electrum. Tomorrow I'll try installing the old version and checking if it's possible to change the directory location/name. Will also check if there are any directories inside that directory that would result in reliable search (automatically named rather than user named)

Thanks for clues so far

I checked through command line (for now accessing like this) and didn't find anything. But I realized I didn't check 32 bit version of Program Files (x86) correctly, it's there so not portable. Where could the wallet data be saved then if not in Roaming? Registry? Or could the folder have been changed?


I choose "Standard Wallet" and "I already have seed". Then I type 12 words in the textbox (corrected the 2nd number in 1st post). But the "next" button stays gray. I can only go further if I select "BIP39" in settings below the textbox. But it says "checksum: failed" below the textbox and if I click "next" and "Detect Existing Accounts" says "No existing accounts found", if I click next I'm asked for new password which I stopped at because I'm not too sure this is correct path.

I'm quite sure there are no other wallets where these words could have been used, but they may be for some other app (someone's messy notes unfortunately).

Like I mentioned, 12. Is that the correct number (from what I've looked in Google it is)? I have also some other word combinations noted down but they're either less or more than 12.

As for address, I have something noted down but I'm not too sure it's the address, it's a 34 characters string, apparently the max size of Electrum addresses.

EDIT: I don't see electrum_data unfortunately, just Electrum 2.6.3.exe file and that's it.

Hello,

how do I recover my address from Electrum 2.6.3 from broken Windows 7 installation? I do have access to disk and I believe also 12 words for the seed. I believe it was portable version since I don't see AppData/Roaming/Electrum folder. I tried entering 12 words in latest Electrum 4 but that doesn't seem to work. Do I need some kind of version compatibility or something else?
