Integrating WinCC project into Step 7 project

Dear sir,

i integrated standalone wincc project (V8.1) into STEP7. I used same machine for ES+OS. When i want to compile OS i recieve an error No database Engine avaliable. SQL server (WinCC) is running.

Hello,

I would check that you have all updates for Step7 and WinCC .  Plus, make sure the Windows release number is compatible as this can cause various problems.  I don't find this error anywhere so it is very unique. Could this be related to this particular project?

Thanks,
Steve

Yes, i have all the updates.

Win 11 pro 24H2

Step7 5.7. SP3

Wincc V8.1.3

Hello,

Thanks
