actually i was trying to install the program jdev_suite_121200_win64.exe
which i already downloaded from oracle web site but when i was trying to install it after the first page of installation i got this error CMD property not found in autorun.inf
.
i already tried run as administrator & running the program through the CMD.
searched in Google & oracle forum just gave me this link https://forums.oracle.com/thread/2559818
.which i couldn't get anything useful from it .
The correct answer is do as follow (did it on Windows 8.1 x64):
C:\PROGRA~1\Java\(..your JDK.., in my case jdk1.8.0_20)\bin\java.exe -jar install/modules/ora-launcher.jar DISKCNT=1 JRE_COMPONENT=oracle.jdk;oracle.jre
;Enjoy ;-) !!
