Hello!

After my vacation, I have problem with WinCC flexible SP3 on my PC: If i'm opening project with WinCC flexible stand alone, everything is fine. If i do it from Step 7 - appears only progress indicator and that's all.

I tried reinstall Step7 and WinCC Flexible software in right order, but nothing changed. 

May be somebody can help me, because I don't want reinstall all Windows 7 ( too much useful information on hard drive and not enough time)

Best regards.

If this doesnt help i would deinstall and reinstall the Integration in Step7 component.

good luck

Thanks, Murrof !

I've tried to reset cash of WinCC Flexible, but no results...

As I've wrote before, I tryed to :

1. uninstall both step7 and WinCC flexible and clean register after this operation

2. install first Step7, then WinCC flexible. After this operations WinCC is working fine only in stand alone mode. If I'm trying to start it from Step7,appears status bar,then became full, but window of WinCC not appears after that.

May be any ideas?

Best regards....

Hello igor_a

Which Versions of Step7 and WinCC flexible do you use exactly?

Hello igor_a

Something must have happend so could it be that you have activated the WIndows Updates.

Are there any Windows Updates in the last Time?

Perhaps you can use a System Recovery Point which are mostly created before a Win Update is installed.
