Hi Brian,
I have few questions on ImageIO.

1. Why does this utility have to be installed in the JRE's folder structure? Is there a reason why it wouldn't work if the jars are in the classpath and the native dlls in the PATH environment variable?

2.What is the impact of installing a JRE patch after this product is installed in JRE?

Both should work.

Your previous installation is history.

There is also the possibility of a WebStart installation:

I have set the native dlls in PATH environment variable. JAI is not able to pick the native libraries. Is there any way to use native acceleration other than installing it in JRE folder?

That should work. I have done it this way before.
