Today I try to download Electrum but this happen any suggestion what is going on
Which version of Electrum and where did you download it from?
Here you can find older versions of Electrum (don't forget to uninstall the one you currently have installed if you decide to try out other versions). Users seem to encounter this issue on Windows 7 and Windows 8.1. The dialog box from the image you uploaded suggests that you use Windows 8.1. Make sure that your OS is up-to-date.
