Hello Ahmed,

Yes, you did all instructions from this FAQ. But you said "uninstall SQL Server of WinCC Flex...". but maybe you must uninstall first Flex and then... Take a look at

It is imperative that you keep to the following installation sequence when you install WinCC V6.2 or WinCC V6.2 SP2 and WinCC flexible 2008:
WinCC V6.2 or WinCC V6.2 SP2
WinCC flexible 2008...

Hope this will helps.

Best regards

It is imperative that you keep to the following installation sequence when you install WinCC V6.2 or WinCC V6.2 SP2 and WinCC flexible 2008:

1. WinCC V6.2 or WinCC V6.2 SP2
2. WinCC flexible 2008

If you have already installed WinCC flexible 2008, consider the following procedure.

<<< Remedy:
You can only install the SQL server from WinCC V6.2 or WinCC V6.2 SP2 if the WinCC flexible instance of the Microsoft SQL Server 2005 Express Edition was deinstalled. WinCC flexible 2008 does not have to be deinstalled.

Procedure:
The table below describes the deinstallation of the WinCC flexible instance of the Microsoft SQL Server 2005 Express Edition >>>>

please note that in the remedy item he said,Ineed not to uninstall the whole wincc flexible 2008 ,
just uninstall part of it .
in our company my friend can install SQL server 2005 without uninstallingflexible 2008.
thank you.

Hi ahedmae94,

ahmedmae94

my fiend in the compamy succeed to install the same source on his laptop

hint, 1) my fried has the same windows

2) I made uninstall to SQL 2005 of WINCCFLEXIBLE before install the new SQL

If I understood well you are going to install PCS7 over station where WinCCFexible installed

please note that in the remedy item he said ,I need not to uninstall the whole wincc flexible 2008 ,

just uninstall part of it .

Yes, you right....but PCS7 is not compatible with WinCCFlexible (in any versions), that means you don't have to install both in same partition (SQL instances is not the only difference, but Simatic NET and other modules too).

in our company my friend can install SQL server 2005 without uninstalling flexible 2008.

You should be able to install both maybe, but I'm not sure both will woks fine in every condition and you could get trouble after time (or when you are going to build some particular configuration)

Your friend has been able to install it, i trust you....can you tell both computer are same configuration? (same application, same version for all of them, same user right, same HW....and more and more).

At the end: if you need WinCCFlexible and PCS7 you have to install them on different partition, if you don't need WinCCFlexible go to uninstall it completely following correct procedure
