About creating installer for maxscript(in 3ds max)

Jeff hannah wrote a great doc about this.And using wizard you can build most of this installer.But there issues.

1.When using codes to detect 3ds max version and directory in windows registry,I am not sure where to put these codes:

ReadRegStr $TempPath HKCR "3dsmax\DefaultIcon\" ""

StrCpy $INSTDIR $TempDir -30

,which are to get this registry key and assign it to a NSIS value.But,where should I put these lines.

2.That's the same situation with detecting whether 3ds max is running and suggest users to close it if it is running.Below are scripts that Hannah suggests:

Push $9

loop:

found

FindWindow $9 "3dsmax"

IntCmp $9 0 installMaxFiles

MessageBox MB_YESNO ‘Max is running. Close it?’ IDYES closeMax IDNO done

Sleep 1000

Goto loop

closeMax:

SendMessage $9 ${WM_CLOSE} 0 0

Sleep 1000

IfErrors done installMaxFiles

installMaxFiles:

<File installation lines go here>

Done:

Pop $9

I am not sure where to put them.

Please give me some elaborations,thanks a lot!

My project script is like this(runs good):

Just want to know where should I add the directory registry key variable and statements and the if-the-program-is-already-running detecting scripts into the main projects.

BTW,I am using HM NIS EDIT.
