We are trying to download LIFA for labview 2013 Version 64 bit but it constantly shows error , could you please help us with this.
I have no problems in downloading the package.
Are you allowed to download from a FTP server?
And a side note, the LIFA package is not supported any more, you should use the LINX package.
LINX is supported by the https://www.labviewmakerhub.com/
Then you might not be able to download from a FTP server.
Contact your IT department to verify that you are allowed to download from FTP servers.
