What exactly are you trying to do? Would running the daemon through WSL work for you?

Telariust · 2019-07-21T11:31:57Z

maybe python36 in 2019? but there are other factors

checked win7x64, cmd as admin

if try run daemon under windows (according to official manual)
C:\1>electrum-3.3.8-portable.exe daemon start
..get back popup-qt

Fatal error detected
Failed to execute script run_electrum

after googled, ./run_electrum - old problem for windows

but use simple fix - run it without start opt
C:\1>electrum-3.3.8-portable.exe daemon
and now in task manager u seen 2proc
dont forget load_wallet
C:\1>electrum-3.3.8-portable.exe daemon load_wallet
after this - rpc full ready!

if would need, add -w [custom_path_to_wallet]

if need close
C:\1>electrum-3.3.8-portable.exe daemon stop

Electrum daemon fully works in Windows? Daemon starts, but the json rpc api does not function. Am I wrong?

Telariust · 2019-08-11T08:44:31Z

I declare - Electrum daemon fully works in Windows! I am using it now!
(there are just some unobvious details)
(what do you mean by "fully works"?)
(if you mean server electrumX and its server commands, then this is completely different)

Daemon starts, but the json rpc api does not function

json rpc api (after secfix 3.0.5)

used rand port
used rand password
not load_wallet on run (but we can load wallet under rpc, if know right port and pass!)

ok, explain, step-by-step

FAQ, how run Electrum in daemon mode with json rpc api under Windows.

success tested on win7x64, run cmd/.bat as admin

download electrum
i used electrum-3.3.8-portable.exe
i dont tested full install ver, but i think - not diff
run it and create wallet
with seed - better
if import privkey, some command correlation with seed dont be work(example, getseed)
if import pub/xpub, some command correlation with privkey dont be work(example, signtransaction)
close it
goto wallet dir, open config, example ./electrum_data/config
add strings

    "rpcpassword": "myrpcpass",
    "rpcport": 7777,
    "rpcuser": "user",

rpchost not need, all works without it, but u can try 0.0.0.0 or 127.0.0.1
rpcpassword may already be. in base64 form. this is misleading - you DO NOT need to convert your new pwd to base64, and does not affect the basic-auth rpc! just electrum generates a rand pwd from raw bytes and presents them in base64 for convenience.
wrote the new pwd in plaintext and for rpc - too, as it is.
or use default rand pwd as it is, without any decode/encode.

create some .bat files
create _start-rpc.bat (if want gui)

start electrum-3.3.8-portable.exe
timeout /T 10
start electrum-3.3.8-portable.exe daemon load_wallet

create _start-rpc_as_daemon.bat (if want not gui)

start electrum-3.3.8-portable.exe daemon 
timeout /T 10
start electrum-3.3.8-portable.exe daemon load_wallet

create _stop-rpc.bat (if u want correct close)
start electrum-3.3.8-portable.exe daemon stop

if u want use custom path to wallet, use -w
start electrum-3.3.8-portable.exe daemon load_wallet -w /path/to/my/wallet/dir
run _start-rpc.bat or _start-rpc_as_daemon.bat
now in task manager u seen 2proc of electrum, it norm
try connect to rpc, try some commands - all must work
all work on top fork! success tested on
ElectrumSV-1.2.1-portable
Electron-Cash-4.0.7-portable
(but .bat not auto close, because stdout on forks tied to cmd parent proc, but it not big problem)

profit! hoho!

I thought I'd check your prescription. tried telnet and VS2019 to read response headers and error description.

win 7 х64 prof / electrum-3.3.8-portable.exe

my conf

"rpcpassword": "user",
"rpcuser": "user",
"rpcport": 7777,

my bat start file

start C:\Users\user\Downloads\electrum-3.3.8-portable.exe daemon --testnet
timeout /T 10
start C:\Users\user\Downloads\electrum-3.3.8-portable.exe daemon --testnet load_wallet -w 'C:\Users\user\Downloads\electrum_data\testnet\wallets\default_wallet'

try for me - telnet
telnet 127.0.0.1 7777

if you remove the daemon key, the GUI opens correctly and the wallet is loaded. This proves that the file addresses are correct. deamon does not work in any of the options.

harryqt · 2022-03-02T10:14:06Z

@Telariust It worked.. Thank you..

Telariust · 2022-03-03T16:45:53Z

-w 'C:\Users\user\Downloads\electrum_data\testnet\wallets\default_wallet'

To be honest, I did not check the performance -w key, but..

CMD in Windows requires the use of double quotes;
Using an escape slash in a path is potentially problematic;
(typical mistake for users nix2win)
Therefore, your wallet did not load at all, and as a result
Try -w "c:/path/wallet"

electrum-4.4.3.exe daemon -d

This works for me now (little changes from https://electrum.readthedocs.io/en/latest/cmdline.html):

start electrum-4.4.3.exe daemon
[wait until 2 processes raised]
electrum-4.4.3.exe getinfo>2_getinfo.txt
electrum-4.4.3.exe stop>3_stop.txt

Options "-w", "-D" or "--dir", "-v", "daemon -d" did not work at all... more details here: #8429

`-d` is not supported, due to missing os.fork related: #5511

SomberNight · 2023-05-16T12:30:31Z

Note that the daemon can be run:

in the background (in "detached" mode):
$ electrum daemon -d
- this uses os.fork() and hence is not supported on Windows
or in the foreground:
$ electrum daemon
- this should work on all platforms (including Windows)

I've added a better error message telling users to try without -d in 68eaa68.
