Dear all,

I am having some issues to install WinCC Unified V19. When I try to install it, the message in the attached picture appears. 

Currently, I have the following softwares installed:

V13:

   - TIA Portal SP2 Update 4

   - Step 7 Profesional SP2 Update 4

   - WinCC Advanced SP2 Update 4

V14:

-TIA Portal SP1 Update 10

- Step 7 Basic SP1 Update 10

-WinCC Advanced SP1 Update 10

V16:

-TIA Portal Update 5

- Step 7 Professional Update 5

-WinCC Professional Update 5

 -Sinamics Startdrive Advanced Update 5

 V17:

-TIA Portal

- Step 7 Professional 

-WinCC Advanced

In the past I also had some problems when trying to install a newer version of WinCC of the same type (Advanced, Basic,...) as an older version of the software.

I tried to use TIA Portal softwares in a virtual machine, but this works too slow whenver I am online with the PLC.

What happens if I uninstall previous version of WinCC to install WinCC Unified as requested in the enclosed picture? I would not like to install older versions, since I still need to provide support to our customers with those ones.

Thank you in advance

Best regards
