I posted a fix to this problem a while back. Just rename the executable to "electrum.exe" and the error you see will go away.

Footnote: Next time you may want to try the excellent search feature that Bitcointalk provides to look for a solution to your problem. Many time the solution is out there if you just take the time to look for it.

Standalone Executable for Windows gives me the following error:

Microsoft Visual C++ Runtime Library
Runtime Error!
R6034
An application has made an attempt to load the C runtime library incorrectly.

some problem with version 2.0.4

I am running electrum 2.6.4. It is now July 20, 2016 and the error is still there. Obviously there has been no effot to fix the problem....so on to a different wallet.


Do you WAN'T to alienate your users? Because this is how you alienate your users.

Is there a limit to the number of accounts a person can create in a single wallet on Electrum 2.3.2 ?

I created two accounts and funded both of them then tried to create a third account but its not being created.

I selected 'New Account' from the menu, entered a name for the account and then nothing happens, no new pending account is being created.

Hi,
XDN-dev team made a DigitalName  JSON alias API for any cryptocurrency http://digitalname.org

With DigitalName you can link your Bitcoin address with any URL.

Here is a first sevrices that use DigitalName API http://xdn.io

New DigitalNote XDN GUI wallet has a digitalname support https://github.com/xdn-project/digitalnotewallet

Will be very glad if your will integrate DigitalName JSON alias API with Electrum.

Thank you.

@Muhammed: thanks, I will try to get help in the official HW.1 thread
Anyway,  on the same PC under Linux everything is just fine.
Also, under win7 btchip-python is not very stable: I tried it five times: 4 times it worked OK, then it gave:
USBError: [Errno None] libusb0-dll:err [_usb_reap_async] reaping request failed

The problem is I am not getting this error. I think it has to do something with your installation. Hope you will get an answer/solution from 'btchip'.

Please post doubts and questions about HW.1 in official HW.1 thread. https://bitcointalksearch.org/topic/now-available-btchip-ledger-hw1-bitcoin-hardware-wallet-in-a-usb-smartcard-134999

Sorry! I am unable to help you in this. You may want to try wiping the dongle by entering 3 wrong pins and create a new seed with Electrum but I think the problem is something else.

I tried to run pyusb again:
Code:
cd pyusb-master\tests
python testall.py
PyUSB ValueError: No backend available

I Googled to this error, and found: http://stackoverflow.com/questions/5152133/pyusb-backend-not-accessible
It said that "You need to install libusb-1.0, libusb-0.1, or openusb as a backend to pyusb."

I downloaded libusb-win32-bin-1.2.6.0 earlier. I tried now:
Code:
cd libusb-win32-bin-1.2.6.0\bin
inf-wizard.exe

create a driver kit for
Vendor ID        Product ID      Description
0x2581            0x2B7C          Plug-up

Then installed the created driver.

Now pyusb tests run witjout errors.
Also, btchip-python is operational, gets back the firmware version.


When I start Electrum, and enter the PIN of HW.1, then the following window is displayed:
Computing master public key

and I also get the following error in another window:
[Errno None]  libusb0-dll: err [_usb_reap_async] timeout error

Please help! How to go on?

@Muhammed: "IIRC" - I asked you to post a build, not to "If I Remember Correctly"...
How do you set up btchip-python, cython, etc under Windows?
It is still a question. Please help!

I can't access my PC for a while, so I don't remember each and every dependencies. Anyway, like I said, if you want to install BTChip-python, download it, point to that directory and run python setup.py install. If you unmet dependencies, it will give an error "Import error: No module named ". Search in internet, download zip/.py file and install it by running python setup.py install.

One of the dependencies I missed is Cython-hidapi.

@Muhammed: When you will be near your PC, please post me the necessary steps. THANKS!
I do not know how to install e.g. btchip-c-api or btchip-pythopn under windows. Under linux I can use
sudo apt-get install libusb, etc... what should I do under windows? Where are the necessary libraries?
What should I use to compile the sources? What is the compilation environment? mingw?

IIRC everything is in Python environment. You just need to change directory to the folder you need to install and run python setup.py install in most cases.

Read "README" in BTChip-python Github repo to see dependencies.

https://github.com/LedgerHQ/btchip-python/blob/master/README.md

Some of the dependencies for Electrum 2.0 are

 • Python 2.7
 • Python setup tools(incl. pip)

A short FYI— as of Python 2.7.9, setup tools/pip are (finally!) bundled w/Python (see PEP 477).

Thank you!

@Muhammed: How did you compile it under Windows? Can you help me?

I am away from my PC, so I can't tell which all dependencies are needed. If a dependency is not installed, it will show when compiling. Download it and install it manually.

Some of the dependencies for Electrum 2.0 are

 • Python 2.7
 • Python setup tools(incl. pip)
 • PyQt
 • ecdsa
 • slowaes
 • BTChip-python API.

I can't recall all dependencies. Like I said, it will show "Import error: No module named abc" if you haven't installed "abc". When it does, search that module in internet, download and install it.

i have installed electrum-2.0-setup.exe under win7 professional.
When I start the program, and  the "Select your hardware wallet" screen is displayed, only Trezor wallet can be selected.

Haven't you installed BTChip-python?

P.S. If you have successfully compiled Electrum and want to auto-start it when windows open, follow this:

#1. Create a ".bat" file and put this code.
Code:
cd location-to-your-electrum-folder
python electrum
#2. Click the Start button, click All Programs, right-click the Startup folder and then click Open.
#3. Drag the .bat folder file to Startup folder you opened.

Didn't get your first question. I compiled myself and yes, it is Win7(Ultimate).

I am trying Electrum 2.1.1 with HW.1
After some minutes I get: "Exception: Timeout"
What should I check or do to make it work??!!!
Please help.

----
Side note:
In the same Win 7 environment,
Electrum  2.1.1 an HW.1 works perfectly under Ubuntu 14.04 LTS in a VirtualBox environment.
I have btchip-c-api, btchip-python and electrum.
I can post the make script to anybody, who is interested.

In 2.0, HW.1 works fine for me. BTChip C API isn't needed for Electrum.
