If VS2013 has trouble checking out a license, you can follow the first step here: 

        For configuring to support strong cryptography > press Windows key + R > type regedit > navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft.NetFramework\v4.0.30319 > add a new registry entry named SchUseStrongCrypto > set its type to DWord > set its value = 1.(or creating a new registry entry by using PS command)
        
        For enabling TLS 1.0 > press Windows key + R > type regedit > navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols > TLS 1.0 > Client > Enabled DWord value 1.
        
        Sincerely,
        Anna
