ReadRegStr $R0 HKLM \

StrCmp $R1 '4' 0 lbl_error

StrCpy $R1 $R0 3

StrCmp $R1 '4.0' lbl_win32_95
StrCmp $R1 '4.9' lbl_win32_ME lbl_win32_98

lbl_win32_95:

you should call this function in your section, here's your code:

Section "your_section" your_section_id
Call GetWindowsVersion
Exch $0
StrCmp $0 "noNT" 0 NT
File /a "D:\MPC9598ME"
Goto done
NT:
File /a "D:\MPCXP"
done:
Pop $0
SectionEnd

Function GetWindowsVersion
Push $0
ReadRegStr $0 HKLM "SOFTWARE\Microsoft\Windows NT\CurrentVersion" CurrentVersion
IfErrors 0 NT
StrCpy $0 "noNT"
Goto done
NT:
StrCpy $0 "NT"
done:
Exch $0
FunctionEnd

that's all you need, to difference between winnt-systems (windows nt/xp/2003) and win98-systems (windows 95/98/se/me).

Functions are to be called in a Section. So in a Section, use the command Call and use StrCmp and File commands to choose what file each one do. Example (Get the code behind "Section" commands and put inside your section if you already have one):

Section

Call GetWindowsVersion
Pop $0

StrCmp $0 "95" +3
StrCmp $0 "98" +2
StrCmp $0 "ME" 0 XPFile

  File /a "D:\MPC9598ME"
  Goto End

XPFile:

StrCmp $0 "XP" 0 NotAvailable

  File /a "D:\MPCXP"
  Goto End

NotAvailable:

; Put a message if you want to warn
; who is not using Win 95, 98, ME or XP.

End:

; Other codes
