V4 is tricky to install. I think we all had problems. I know I sure did.

Here is a picture tutorial. I think you might be installing into the wrong folder (the actual runtime instead of the actual program folder itself). Which causes a runtime within a runtime.

Hope this helps.  Don't forget to do the initialization after installing.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
