Can you tell us the build date of your copy of EViews 6? You can find this out by clicking on Help->About EViews.

Jun 3 2008 build.

there are only two options in about Eviews, one is ok and the other is credits. I clicked both of them, but doesn't work.


thank you ~~

You should update your copy of EViews. That might fix the problem for you.
