WinCC V13 prof installation error

Davids

Hi,

Today I try to install WinCC V12 into my PC and it got some problem. It show me error as below.

"WinCC Professional V12 cannot be operate in parallel with the currently installed version of 'WinCC Professional' and 'WinCC Runtime Professional'. Please remove 'WinCC Professional' and 'WinCC Runtime Professional' in order to operate WinCC Professiona V12."

I had completely remove WinCC Professional V11 and Runtime Professional V11. Still it not able to proceed V12 installation. Any idea on how to fix it problem?

My PC Setup is Windows XP SP3.

I have the same problem but with WinCC Professional V13 and WinCC Professional V12. I did a complete unistall of TIA PORTAL V12 and delete all folders of TIA PORTAL V12.

In the "cmd" type "regedit" and look under the files below:

In Windows 7 32-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Siemens\Automation\_InstalledSW\
TIAP11\TIA_ES_V12\PrivateProperties\INST_TYPE_LEVEL_INTERNAL

In Windows 7 64-bit:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Siemens\
Automation\_InstalledSW\TIAP12\TIA_ES_V12\PrivateProperties\
INST_TYPE_LEVEL_INTERNAL

Make a backup of these registers and delete. Finally you can install your WinCC.

Split from WinCC V12 installation error.

The Registry Key in TIA V14 ES folder was also causing same issue for WinCC Tia V13 SP2 installation.

Removing the key from V14 helped install the V13 SP2 WinCC Professional.

Thanks

Also note, in Corporate PC, connection to User drives is necessary to continue installations for MSI.
