We are in the process of a server move, both to a new host and from a Server 2k8 box to a Server 2012 box. The server in question has a few drives that hold our sites and some utilities. These drives were duplicated exactly during the move. Data, folder structures, and permissions should all be identical.
Recently, when running a Jenkins task on this server, I found the following in the log:
G:\Websites\PathToWebsite>G:\Jenkins\Tools\7z a -tzip Website_PROD_Backup_20140311_.zip
7-Zip  9.20 Copyright (c) 1999-2010 Igor Pavlov 2010-11-18
Error: 7-Zip cannot find the code that works with archives.
7-Zip is installed on the server and I can do the actions it's trying to do from the GUI. I'm a developer and am not used to troubleshooting something like this, and Google for the specific error hasn't led me to any resolution.
The closest match I could find is a site that says the command-line tool needs a few .dll files if it's less than 150K. I found the tool at the referenced path above and it was over 150K. I copied the .dll files from the install directory to that directory anyway. This did not fix the issue.
What should I do to fix this? I really need 7-Zip to work from the command line or significant parts of our build/deploy process will have to be done by hand.
