I need to control what is displayed during installation on progress label. For example on install phase we unzip an archive. On panel is displayed our label (Installing...) follow by "unzip archive xxx.zip" (I don't remember the text exactly by is says the action and the file name). I want to have full control of text displayed or to suppress the progress text.

We have 2008 VP1 Enterprise version. Please let me know how can I do this (also if we need to upgrade to a new version is ok).
