Remove the Installation

You may need to uninstall your environment. Re-run the Setup Manager to remove the product.

How to Uninstall

Removing the product is essentially a reversal of the installation and configuration process. The Setup Manager will identify the components installed and remove them from the target system.

Removing Components

If you have installed the product in a distributed environment, uninstall all client components first. Then uninstall the server components.

Uninstalling steps:

1. Ensure that all related processes, such as Server service, are shut down.
2. Run the Setup Manager ("%PROGRAMFILES%\K2\Setup\Setup.exe" or browse to Start > All Programs > K2 > K2 Setup Manager) and select the Remove K2 option.
3. Follow the on-screen prompts to complete the wizard.
4. Reboot after the uninstall.

Manual Environment Clean Up

After uninstalling the components, there are some manual steps to clean up the environment. They are as follows:

1. The product menu item is left in the Start menu after the uninstall. Delete this menu item by right-clicking the Start menu and selecting Explore / Open All Users. Then browse to Programs folder and delete the K2 folder.
2. The SourceCode assemblies remain in the Global Assembly Cache (GAC). Delete all SourceCode assemblies from the C:\Windows\Assembly folder.
3. The SourceCode registry key remains after uninstall. Delete the registry key located at HKEY_LOCAL_MACHINE > SOFTWARE > SourceCode.
4. The product folder structure remains. Delete the folder located at C:\Program Files\K2 (this may differ depending on your installation location)
5. The database remains in SQL Server, which means data is preserved. To restore the server to a clean state, delete the database. If you need to preserve process or logged information, make a backup copy before deleting the databases.
6. The machine.config file has remaining SourceCode entries. Edit the machine.config file, located at C:\Windows\Microsoft.NET\Framework\v2.0.50727\config, and remove all sections that mention SourceCode, including the <sourcecode.configuration> node. Be sure to save your changes to the file.

Validating the Uninstall

After uninstalling the product and performing the manual steps, reboot the machine. Then ensure the environment does not have any product related components left. Use the checklist below:

1. Make sure no product Databases are present on the SQL Server.
2. Make sure the product menu items are not present under Start > Programs.
3. Make sure no components are present in Add / Remove programs (Start > Control Panel > Add /Remove Programs).
4. Make sure no SourceCode nodes are present in the machine.config file.
5. Make sure no SourceCode assemblies are in the GAC (C:\Windows\Assembly).
6. Make sure no product folder is located under Program Files.

Considerations

• When uninstalling components from your environment you must follow the specified order of events to ensure a successful removal of all components.
• Uninstalling the product will remove all components from the target system. If you want to remove just a single component, select the Modify option from the Setup Manager.
• If the components are being removed from a distributed environment, then removing the components from the target system may cause issues in the associated environment /s. There are several manual clean up steps to ensure the environment works properly, as already shown in the sections above, be sure to follow them closely.
• If you have multiple servers in a distributed installation and uninstall one of them, the remaining servers in the farm may raise errors such as "cannot connect to [name of uninstalled server]". This error resolves automatically after a few minutes as background processes disable the uninstalled server’s entry in the server table.
