In the Windows Display Settings if the "Change the size of text, apps and other items"
property is changed and the value is not equal to 100%, then NPrinting has problems to embed the Excel application inside it.
This will prevent you to create or edit any Excel report and might result in the error "NPrinting Designer can't find a supported template editor for the file"
. The application will hang and you will need to kill the process manually. However, in some environments no errors are seen and the Designer process and the Microsoft product process (i.e. Excel, Word, etc) will remain in hung state when inspecting via Task Manager.

This issue happens because the changing of the system property modifies the DPI of the display and the NPrinting application doesn’t support this MS Operating system Windows 10 change. There are no plans to modify NPrinting Designer to accomodate this operating system change.
There are three workarounds to fix this problem:
- Set the "Change the size of text, apps and other items" property equal to 100% in the main display.
- If you have 2 monitors set the main display to be the one that has the property equal to 100%. If problem persists, set all monitor to 100% of size.
- Enable the "Disable display scaling on high DPI settings" property, that you can find in the properties of the NPrinting.exe application:
C:\Program Files (x86)\NPrinting\Client, in "Compatibility” tab
C:\Program Files (x86)\NPrinting\Designer , in "Compatibility” tab

If available, also click on "Change high DPI Settings"
and enable "Override high DPI scaling behaviour"
