Script execution error WinCC Prof v17 after upgrade to upd5

Hello everybody!

We have button on Screen window with Click event "Activate screen" (screen name "Settings_(1)").

Loaded event "execution VBSscript" configured on screen "Settings_(1)" and executed with errors "HMIRuntime.get_ActiveScreen:Unspecified error (Неопознанная ошибка)". So, we can't use scripts with access method "HMIRuntime.ActiveScreen.".

This issue was appear after we install Totally_Integrated_Automation_Portal_V17_Upd5. Previous version we used V17 without updates and all works fine, without errors.

Does anybody have any solution for this problem?

Thanks.

Since you have upgraded and it was working fine before, I recommend:

- Make a backup of the project

- Delete the IM folder (How do you delete the IM folder of your TIA project?). The IM folder contains temporary files that may not be overwritten correctly (through replacing graphics, for example). The folder and all the files in the folder are recreated when you compile with a complete rebuild. Therefore, deleting the IM folder offers a remedy for existing inconsistencies.

- Compile everything again
