Sometimes your downloaded instrument files will first appear as a single or multi-part archive in .zip or .rar format, especially for older downloads. Most operating systems should be able to properly extract these files by double-clicking them (for multi-part archives, you only need to double-click the first one and the rest will automatically be processed as long as they are all located in the same directory). But if you’re having trouble opening them, you can use one of the following recommended free file extraction utilities:

7-Zip (Windows)

WinRAR (Windows)

Note: Any .rar files downloaded through Continuata Conduct can be safely deleted once the library is installed and working.
