Windows 7 What is Win32?

[cryptogram]

I tried to install Java JKD after downloading the exe file, but a message came up saying this was not a valid Win32 application. But I don't know what that means.

Some programs related to Windows are 32bit, some are 64bit. Like in my case, you probably need to have both 32 and 64 Java installed, in order for Java to function properly. Check your Java in their homepage https://java.com/en/download/index.jsp

It may take a step or two.
