Electrum 2.0 release

[Muhammed Zakir]

@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 <unmet_dependency>". Search <unmet dependecy> in internet, download zip/.py file and install it by running python setup.py install.

One of the dependencies I missed is Cython-hidapi.

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 Zakir]

Please post doubts and questions about HW.1 in official HW.1 thread. https://bitcointalk.org/index.php?topic=134999.0

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.

[Wotan777]

@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'.

Sorry it this was already asked, I didn't find it.

Why did you decide to not use BIP39?

[dNote]

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.

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.

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.

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.
