A good compression/archival program is not exactly a special piece of software. If it is too difficult for you maybe you should just turn your computer off and take it back to Wal-Mart.
Seems pretty special to me, What use would a mining rig have for it otherwise? Installing it on your main pc is one thing. If your trying to convince me that installing a secondary program on numerous pc's, to save a 3mb download is a good deal. Give it a rest.
Why would you need to do that? Can't download to the file server, extract it, then copy it to other machines on the LAN?
