So I downloaded Electrum Wallet 2.7.18 Standalone Executible, the Windows Installer and the Portable Version and neither of them worked on my Windows 10 PC. I also tried to download previous versions but did not have sucsess. I tried to run it using Windows 7 and 8 compatibility mode, nothing. Just to make sure, I turn off Avast annnd no luck. It wont open, no matter what I do. I did not find any processes on the task manager.
It seems to be a little odd. Searching in forums I coudn't find anyone with the same problem, so I appreciate if somebody who has been through that could help me out!
This must be a problem of your computer and not electrum. I am running Windows 10 since almost it first came out and I am still running Electrum 2.7.12 without any issues at all. Make sure you delete the appdata folder of electrum, uninstall it, update your PC and try installing latest version but it's not a version problem as I already said.
