Installing a Maintenance Release of 360 on Windows Does Not Work


Installing a maintenance release of 360 on Windows which replaces an existing 360 installation does not update 360 to the newer maintenance release version, even though the installer says the installation is successful.


Close all running instances of Tecplot 360. A maintenance release overwrites the existing 360 installation. If 360 is running the operating system will prevent the executable from being upgraded.

Confirm that all running instances of 360 are closed by using Task Manager and looking at the Processes tab. Task Manager is available by typing “Task Manager” in your Cortana search bar on Windows 10, or via Cntl + Alt + Del and selecting Task Manager on all versions of Windows.

When all running instances of 360 are closed, rerun the installer.

Note: The same is applicable for Tecplot Chorus.
