Hi there,

I am trying to install Windchill.

But when I start the installer via RDP on a computer with a 4k monitor, I get this:

Title, side bar and headings are quite readable. 

 

But all input fields (text, dropdown, checkbox, etc. ) a tiny and not readable.

The text lines are only 5 pixels “tall”.

 

Is there a trick?
