Dear- It seems that this is very simple problem, when install IB TWS. When I click the icon "Trader Workstatiom 4.0", there is error message as below (captured png file) Do I need to erase Java 1.8 and install 1.7 again? If so, where can I find it? Appreciated if someone show me any link. -Jay
You need to install the 64 bit and 32 bit versions of java. I am using version 8 release 25 with no problems.
You need the latest java version for x32 and x64 bits (8 version 25) and uninstall all older versions.
