Electrum 3.0.3 crashes on startup El Capitan

[tavitavi]

Hi, I've downloaded Electrum 3.0.3 and put in the applications folder. When I try to open it there's a box saying "please wait" for less than a second, then the application crashes. It's super annoying. Anyone know what this is about?

I updated to High Sierra, problem remains.

Don't mean to hijack your thread, but...

I am holding back on downloading electrum version 3 as I understood it is crashing after downloading on Windows 7 ( I am using 2.8.3).

Anyone know if this issue has been solved on 3.0.3 yet? Or should I wait for 3.1 to come out?

Really want to use segwit addresses, both for fee cost saving reasons and to help out ecosystem (mempool congestion).

I can confirm that Electrum 3.0.3 is working perfectly on Debian.  Its not Electrum so if you are having issues it must be OS specific.  3.0.3 is jammed with great stuff.  Best yet!

I've seen other users say that after downloading Electrum you need to move it to a new folder after it has been downloaded before it will run? I've tried running it on my MacOSX 10.12 Sierra Virtual Machine, and it seems to run fine... although I do have to "ctrl-click" and then select open to get around the MacOSX antimalware thing.

Download the portable version of 3.0.3 and see if it runs... if it runs, the proper windows installer and/or the standalone will run as well... I just recommend testing with the portable version, as it won't touch your current wallets etc... it creates an "electrum_data" directory in the same folder where you run the portable .exe from... so your current files will not be at risk.

You may want to try installing the "fixes" for Electrum to get it to work in Windows 7... I believe it was an issue with redistributables (https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads)...

it is sometimes the "startup" operations that cause errors like this and since there are no user friendly error message it is impossible to say where things went wrong. unless you do a traceback and see step by step where things went wrong.

Electrum saves a couple of things to start your application. things such as position and size of your window (winpos-qt), all your wallet settings including server names, last one that you connected to, recently opened wallet files (this was causing an error for me in one of the versions once), exchange rate and where to get it,...
the portable version that HCP said helps with this. but to fix the issue you need to go to your data directory where your Electrum files are and remove your "config" file. you can make a backup from it then delete it. there is nothing sensitive in this file so don't worry.

Thanks for the advice HCP & Pooya.
