Error autorun

[GK.Design]

Hello I have a problem,

I need to find out how to install packages offline.
One person told me to try Keryx well I dowloaded the ZIP and extracted it and found the file that opens it and dubble clicked and it said "error autorun (something)" and below it said it could not find the autorun application.
So I right clicked selected open with a different application and pointed it to autorun prompt(?) and it still opens up the same error.

Hope I made myself clear.

Im afraid you didnt. Its not even clear to me if you are doing this in ubuntu or windows. Autorun is very much a windows thing.

If this is indeed about ubuntu, then download keryx, extract the folder somewhere, like to your homefolder, and then you can just launch it by doubleclicking keryx_linux_32bit inside the linux folder.
