Hello, I uninstall WinCC Professional V16, install V17 Unified few weeks ago. TIA V17 is working perfectly well.

So today I tried to uninstal V16 and install it again but with WinCC Unified and i have a problem -  Target directory is in red (attached photo) on Component selection Page.

I cant continue installation.

I check windows permissions, my account has Full Control permissions over whole C:/ drive now.

Any target directory i chose is in red.

What can i do?

 Hi

You may have not deleted all the parts, try to do it by TIA installer again.

Refer the video for installation guide here

Unfortunetly i can't run installer for TIA V16 WinCC Pro because i have already installed TIA V17 with Wincc Unified and don't want to uninstal it since Im working on v17 every day. Im afraid I might break something
