If you look in the Redistributables view, there is a Java run-time prerequisite you can add to your project; it contains a condition that might suit your needs...

Hi Robert.
thank you so much. I sincerely appreciate your generosity,

I allready done that thing created new Prereqestor for JRE 1.6,
and done all the steps problem is just , i want to check that if the Machine has higher version then 1.6 , it that time it shoud have to skip the installation of JRE 1.6 but
i am not able to check the version with < opertator

i tried with these also in condition Buider
CURRENT_VERSION > 1.6
CURRENT_VERSION > “1.6”
CURRENT_VERSION > ‘1.6’

so can u please explain me in details , what i have to write as conditon in .prq (prerequstor) file.

Please see, for example, the Prerequisite Condition details for the existing Java prerequisite, which has a similar condition set up, and which you can modify...

Here's a snippet I've been using for some time now, hope it helps;

prototype Get_JRE_Folder(BYREF STRING) ;


function Get_JRE_Folder( JRE_dir)
NUMBER nResult,nSetupType,nRootKey, keyType,nvSize;
STRING keyString, JRE_Version;
begin

RegDBSetDefaultRoot(HKEY_LOCAL_MACHINE);

nRootKey = HKEY_LOCAL_MACHINE;
if (RegDBSetDefaultRoot(nRootKey) < 0) then
MessageBox("First call to RegDBSetDefaultRoot failed: Error in Line 101", SEVERE);
return -1;
endif;

keyType= REGDB_STRING_EXPAND;
//Try to find the Java RunTime first
if (RegDBGetKeyValueEx ( "\\SOFTWARE\\JavaSoft\\Java Runtime Environment", "CurrentVersion",keyType, JRE_Version, nvSize) < 0 ) then
//NO JRE FOUND

// MessageBox("Could not detect Java Runtime Environment, will now launch JRE Installation", WARNING);
return -1;

else
keyType= REGDB_STRING_EXPAND;

//Found JRE
if (RegDBGetKeyValueEx ( "\\SOFTWARE\\JavaSoft\\Java Runtime Environment\\"+JRE_Version, "JavaHome",keyType, keyString, nvSize) < 0 ) then
//MessageBox("Could not detect JavaSoft JRE: RegDBGetKeyValueEx", WARNING);
return -1;

else
MessageBox("JavaSoft JRE has been found.",INFORMATION);
JRE_dir = keyString;
return 0;
endif;
return -1;

endif;

end;
