I can't update WinCC Unified V17.0 to update 2. It shown me the update 2 required WinCC Unified PC V17.0 installed but it already installed in my PC, even though I selected repair or uninstalled/reinstalled the completely TIA software but it is still the same behavior.

Have anyone of you guys ever faced this trouble ?

What is a problem ? and how can I deal with it ?

Thank you in advance.

PS. it also occurs once I tried to install the update 1.

Hello Everyone, I have the same issue. PC clearly has installed WinCC Unified V17.0 (visible in control panel and is used every day) but during installation it shows this very message. Also, this is not the case just on my PC. I tried on two fresh VMs and this happens over and over.

This issue is persisant with every update  I tried (upd1,upd2 and upd4). 

Hi All.

I have the same problem.I wonder if this update is included in TIA Portal V17 Upd5? because I installed it before and maybe there is no problem at all?
