مشکل step7 در Wincc flexible

جواب تو زیمنس این گذاشته ولی نفهمیدم که چی گفته
Today the Siemens germany tecnician solve my problem:
to solve it, it must be manually register two DLL: “Step7.Utah2AutApiSrv.dll” and “Step7.S7INSInfoSrv.dll”. Both of this dll are into winccflex directory (on my machine “C:\Programmi\Siemens\SIMATIC WinCC flexible\WinCC flexible 2007”). For manually register you need open a ‘command prompt’ windowsand go into the specify winccflexible directory, and execute the command “regsvr32 Step7.Utah2AutApiSrv.dll” first, and the same command with the other dll.
After this you need to download, from microsoft, the DWMAPI.DLL and place this into “c:\windows\system32” directory.

After this operation, the winccflex integration start to working normally.

Here I report the information about the windows dll missing, from the Siemens tecnician.
(Thank-you very much mr. Riedl-Siemens)
