With the installation of Service Pack 3 for WinCC flexible 2008 and WinCC (TIA Portal) V11 SP2 on HP notebooks there are incompatibilities with the HP keyboard driver. If you uninstall the keyboard driver, this might mean that a block of the task switching function configured in WinCC flexible 2008 or WinCC (TIA Portal) V11 SP2 no longer works on the notebook.
If the PC can no longer be operated during installation ("CTRL + ALT + Delete", keyboard and/or mouse), you can operate the PC via a remote connection if one has been established beforehand. Then you can also apply the following remedies via the remote connection.
- WinCC flexible 2008
- WinCC (TIA Portal) V11
The following products are affected:
- SIMATIC WinCC flexible 2008 SP3 Compact/Standard/Advanced
- SIMATIC WinCC flexible 2008 SP3 Runtime
- SIMATIC WinCC (TIA Portal) V11 up to SP2 Update 5
1. Remedy for WinCC flexible 2008
You have two ways of avoiding this incompatibility in WinCC flexible 2008. Either you uninstall the HP keyboard driver or you uninstall the keyboard driver that is installed along with WinCC flexible Runtime or the simulation.
Both alternatives must be executed at the latest before the concluding restart of the PC after installation of WinCC flexible 2008 SP3.
If the restart after installation has already been made and the system no longer starts or you have a blue screen, follow the instructions given under "Run Windows Repair".
The alternatives are described below each with their advantages and disadvantages.
1.1 Uninstallation of the HP keyboard driver
1.2 Uninstallation of the keyboard driver of WinCC flexible Runtime
1.1. Uninstallation of the HP keyboard driver
With this alternative the task switching function is retained for WinCC flexible Runtime. Uninstallation of the driver might limit use of the HP special keys. To continue with this alternative you must uninstall the HP keyboard driver as follows before installing WinCC flexible 2008 SP3.
||Open the Windows Device Manager.
||Navigate to: Keyboards, "Standard ... Keyboard with HP QLB " and right-click to open the Properties.
||Open the "Driver" tab and select Roll Back Driver for the HP keyboard driver.
||Confirm the dialogs that open with "Yes" and "OK".|
The result is that the standard Microsoft keyboard driver is used.
||Quit the Device Manager and restart the PC.|
1.2. Uninstallation of the keyboard driver of WinCC flexible Runtime
This alternative retains the HP special key functions. Uninstallation of the driver disables the task switching function for WinCC flexible Runtime. To continue with this alternative you must uninstall the keyboard driver for WinCC flexible Runtime as follows before restarting the PC after installation of WinCC flexible 2008 SP3.
||Open the input prompt (CMD) with administrator rights.
||Open the driver directory. The directory path for the driver directory depends on the installed operating system.
Driver directory on 32-bit operating systems:
"C:\Program Files\Common Files\Siemens\HmiRTmDriver32"
Driver directory on 64-bit operating systems:
"C:\Program Files\Common Files\Siemens\HmiRTmDriver64"
||Remove the driver with the following command:
For the WinCC flexible Runtime:
"FwKbdRTmRegister.exe -r fwkbdrtm -d fwkbdrtm.sys"
||Quit the input prompt and restart the PC.|
Run Windows Repair
If WinCC flexible 2008 SP3 is already installed and the ensuing restart already made, the system might no longer start or you get a blue screen.
Below is the procedure for this case.
You need an additional USB keyboard for the steps below.
||Run a "Startup Repair" (displayed after boot problems) or start the HP notebook from the Windows DVD.|
||Select the "Launch Startup Repair" option after the "Startup Repair" or after the start from the Windows DVD.|
||Interrupt the "Startup Repair is checking your system for problems" message with "Cancel" (abort search).|
||Acknowledge the "Do you really want to abort?" question with "Yes".|
||Select the "View advanced options for system recovery and support" option.|
||Select the USB keyboard and log on.|
||Open the input prompt (CMD).|
||Switch to the driver directory ("C:\Windows\system32\drivers", for example).|
||Rename the HP driver: "ren hpqkbfiltr.sys hpqkbfiltr.sys_".|
||Quit the input prompt (CMD) and restart the PC.|
||Use the USB keyboard or USB mouse to continue with Alternative 1 or 2.|
2. Remedy for WinCC (TIA Portal) V11
The defective keyboard driver is bug-fixed in TIA Portal V11 SP2 Second Edition Update 2 onwards. If you install an earlier version of WinCC (TIA Portal) V11, you will no longer be able to operate your computer.
Make sure that you have the correct version in the start screen of the installation.
- If the abbreviation "SE" is missing as in Fig. 06, you are in the process of installing the incorrect keyboard driver for this version. In this case you should abort the installation and get in touch with Product Support to get version V11.0 SP2 SE incl. Update 2. Install this version and then install the latest update in each case of the service pack in Entry ID 58112582.
- If, however, the abbreviation "SE" does feature in the version designation as in Fig. 07, you are already installing the bug-fixed version. Finish this installation.
