Detect the DirectX's version installed

Author: Joel (talk, contrib)

Description

This will detect the current installed version of the DirectX. Hope that will work with v7 and lower. Bugs? PM

The Script

OutFile "DirectX.exe"
Name "Detect DirectX version"
Caption "Detect DirectX version"
XPStyle "on"
 
Function .onInit
ReadRegStr $0 HKLM "SOFTWARE\Microsoft\DirectX" "Version"
StrCpy $1 $0 5 2
StrCpy $0 $1 1
StrCmp $0 "0" 0 +2
StrCpy $1 $1 "" 1 ; Remove leading 0
MessageBox MB_OK $1
Quit
FunctionEnd
 
Section "-boo"
;
SectionEnd

Thanks KichiK for the "StrCpy" idea :p
