The Snippet
This at the top:
!define JRE_VERSION "1.5" !define JRE_URL "http://javadl.sun.com/webapps/download/AutoDL?BundleId=18675&/jre-1_5_0_15-windows-i586-p.exe"
or for Java 1.6:
; Definitions for Java 1.6 Detection !define JRE_VERSION "1.6" !define JRE_URL "http://javadl.sun.com/webapps/download/AutoDL?BundleId=18714&/jre-6u5-windows-i586-p.exe"
In your MainSection:
Call DetectJRE
And this wherever you want:
Function GetJRE MessageBox MB_OK "${PRODUCT_NAME} uses Java ${JRE_VERSION}, it will now \ be downloaded and installed" StrCpy $2 "$TEMP\Java Runtime Environment.exe" nsisdl::download /TIMEOUT=30000 ${JRE_URL} $2 Pop $R0 ;Get the return value StrCmp $R0 "success" +3 MessageBox MB_OK "Download failed: $R0" Quit ExecWait $2 Delete $2 FunctionEnd Function DetectJRE ReadRegStr $2 HKLM "SOFTWARE\JavaSoft\Java Runtime Environment" \ "CurrentVersion" StrCmp $2 ${JRE_VERSION} done Call GetJRE done: FunctionEnd
