1.8 How to Perform an Uninstall
Introduction
On your computer, you can remove WinCC completely or simply remove individual
components. You cannot remove individual languages.
You can execute the removal via the WinCC product DVD or vial the control panel of the
operating system.
Procedure: Uninstalling via the WinCC Product DVD
1. Start the WinCC product DVD.
The DVD starts automatically if Autorun is enabled in the operating system. If the Autorun
function is not activated, start the program Setup.exe on the DVD.
2. Follow the on-screen instructions.
3. Select "Remove" as the setup type.
4. Select the components that you want to remove.
Alternative procedure: Uninstalling via the Control Panel
1. Open the Windows "Control panel" under the Start menu.
2. Double-click on the "Programs" icon.
3. Click the "Change or Remove Programs" icon.
4. Select the desired entry and click "Remove" or "Change".
All entries of the installed WinCC components start with the prefix "SIMATIC WinCC".
Remove any WinCC options that may have been installed before you remove the WinCC
version.
Microsoft SQL Server 2014
After uninstalling WinCC, the "WinCC" SQL server instance must also be removed. Select
"Control Panel" > "Programs and Functions" and then select the "Microsoft SQL Server 2014"
item for removal.
The use of the Microsoft SQL Server 2014 is only permitted when you have a valid license.
Automation License Manager / MS Update
When WinCC is removed, the following programs remain installed, as they may be needed by
other SIMATIC products:
● Automation License Manager
● MS Update V1.0 SP1
If, after removing WinCC, you want to install an earlier version of WinCC, you will need to
remove both of these programs. Open "Control Panel" > "Add/Remove Programs" and then
select the corresponding item for removal.
