I've been installing and using Java since all there was was Java 1.02. I've installed several versions, most recently Java 7. I have tried to install Java SE 8u25 on a 64-bit Windows 7 system. This fails with a ClassNotFound exception. I've never seen that in any prior Java version. I have found mostly people saying, "Me too," rather than anyone proposing a solution that worked. Any suggestions? Thanks.

Any more info? Does it say which class is not found? Stack trace?

What fails? The actual installation?
Running/Compiling stuff after installation?

Sounds weird to me.
Maybe uninstall java completely, and then install into a 'fresh' environment?

The exception occurs during the installation problem. I never get to compile anything. I also do not see a Stack trace. I am attaching a screen shot of the error that I received. This is pretty minimal, but I'm not sure where I would find more info. Thanks.

Just to check, you DID download the 64 bit version of java right?
I think that error might occur if you are running a 32bit installer on a 64bit machine, or vice versa.

Also I note that this is the Netbeans version of the installer. Maybe its Netbeans rather than java?

Maybe you can get a dedicated java installer without netbeans to see if that works?
