I'm using the MUI Page INSTFILES in my Installer and I want to change the length of the Progress bar and the Position of the "Show Details" Button in it.
Is this possible still using the MUI Page or do I have to make my own custom Page with nsDialogs
?
You can use Resource Hacker to edit ${NSISDIR}\Contrib\UIs\modern.exe
and then use this new UI resource:
!define MUI_UI myNewUI.exe
!include MUI2.nsh
...
The other alternative is to call SetWindowPos
or MoveWindow
with the system plugin at run-time but this is a bit harder to do...
