I downloaded the Electrum wallet and i can't figure out how to receive funds. I have Arcbit and i need to figure out how to send money to the Electrum wallet . When i put the electrum wallet address into the Arcbit it says invalid address, Can someone help me?

I tried to install the electrum wallet to my computer and it was a zip file.
Could someone explain to me how i can install it to my computer?
Thanks

when i go to back it up it say acrobat cannot open files

windows on computer

How do you withdraw from Arcbit?
