Install Multiple Desktop Versions

A common scenario that requires more than a single version of OneStream Desktop installed on the same computer is when your company has set up a testing environment with a new version of the application prior to upgrading production servers. You might need to install an additional instance of OneStream Desktop on your computer to test the new version and still maintain access to the current version.

You can install up to eight instances of the desktop application on a single computer. Each installation instance has a specific named instance embedded in the installer: 0, I2, I3, I4, I5, I6, I7, I8.

Each instance also has a corresponding name in the installation folder and shortcut. The default instance is named 0 and does not have a corresponding change to the installation folder or shortcut. For example, I2 has a shortcut name of OneStream Desktop (2).

NOTE: More than one user can have the same named instance installed. But with a per-machine installation, you must use a named instance that is unique among all users on a machine. The installation attempt will fail if all eight instances are already claimed.
