Dynamically changing the text on the finish screen?

As the title says, is there an easy way to dynamically change the text on the finish screen? I simply want to do a little customization of it, but dynamically

Which text do you want to change?

I simply want to say something along the lines of "This installation requires the Microsoft.Net Framework. Please install the .Net Framework, and then attempt to install this program again"

I guess it would be nice if I could change the title text as well, but it is not neccissary.

Here is an Example:

!define DOT_NET_OK $R0
!define MUI_CUSTOMFUNCTION_FINISH_SHOW OnShowFinish
!define FINISH_ERROR_TITLE "Error installing ${MUI_PRODUCT} ${MUI_VERSION}"
!define FINISH_ERROR_DESC "This installation requires the \
Microsoft.Net Framework. Please install the .Net Framework, and then \
attempt to install this program again."
...
Section "-FirstSection" #This section is hidden
... # Detect in if DotNet is installed if not call abort and set ${DOT_NET_OK} to "0"
SectionEnd
...
Function OnShowFinish
   StrCmp ${DOT_NET_OK} "1" DOT_NET_INSTALLED
   GetDlgItem ${MUI_TEMP2} ${MUI_TEMP1} 1201
   SendMessage ${MUI_TEMP2} ${WM_SETTEXT} 0 "STR:${FINISH_ERROR_TITLE}"
   GetDlgItem ${MUI_TEMP2} ${MUI_TEMP1} 1202
   SendMessage ${MUI_TEMP2} ${WM_SETTEXT} 0 "STR:${FINISH_ERROR_DESC}"
DOT_NET_INSTALLED:
FunctionEnd 

good luck,
Ramon

thx, looks like it is working!
