New message required for MUI_PAGE_INSTFILES

I am using MUI_PAGE_INSTFILES which displays the files as they are copying. I am running a command using nsExec::Exec, the command takes a long time to run. Unfortunately the message displayed above the progress bar refers to the last thing it did, I.e. copying a file etc. I would like to display a different message on this window as my command is running.
Any Ideas?

Use DetailPrint.

Perfect! Many Thanks. Do you know how to hide the text area showing the history of the files it has copied?

You can use ShowInstDetails nevershow.
