Update procedure in Linux primary OS consists of the following steps:
We recommend that you use the Auto-update feature incorporated in Parallels Workstation to be informed when new update is available. Auto-update feature regularly checks the Parallels server and informs when the update is found. See Auto-Updating Parallels Workstation in Linux.
Instead you may check for new updates using Update Wizard or manually on Parallels site.
There are two ways to download an update:
If you use the Auto-update feature, it informs you when the update is available and launches the Parallels Update Wizard for downloading. If you do not use the Auto-update feature, you are able to start Parallels Update Wizard manually. See Update Wizard in Linux.
After you have the update downloaded to your computer, you need to install it. See Installing an Update topic for guidelines.
If you need to install an older version of Parallels Workstation than the one currently installed, in some operating systems it requires to perform a different command than an newer version installation.
