Hello,

as mentioned in the topic i've encoutered a problem with downloading a project created in Tia Portal with WinCC Professional (15.1).

When RT is on I can't download project (no problem with downloading when RT is off) and i get attached error. Problem appears even on new projects so I suspect some Tia configuration problems but I didn't find any solution for that case or even description for that error.

Tia is installed on VMWare Workstation 15 and Win10 Pro without any errors.

Hi MarcinM1103,

Check at first if you Win. 10 version is tested and released with WinCC Professional V15.1
Dow you have the same update on ES und OS
Check all issues from follow FAQ
What should you watch out for when downloading WinCC Runtime Professional from the Engineering Station to the Operator Station (Runtime PC)?

Thank you for Your reply schufri,

I've already check this list of requirements and the only diferences are:

- Windows 10 is "newer" - version 1909
-.NET framework is "newer" - version 4.8.03752

I was told from my local SIemens contact that theese rather are not reasons of unexpected behaviour like that.

I also attach a ss of "regular" download where I always have to check the box to download full project instead of only changes which appears every time.
