Hi rishabh1509,

This error comes on all projects or any specific project ?

Create new small project and check for compilation to confirm proper installation.

this problem is show in every project that i made in earlier.

and in new project i create only one screen and no button or other things...this is not show this problem.

What update of TIA you have done?

What Version of WinCC?

Try a new Installation of SQL Server.
