Issues with trial

[corbinlawrence]

I'm a graphic design student, so this isn't my forte.

I'm trying to use the trial version of ArcInfo for the Interpolation feature so i don't have to work with GRASS. I've had no issues with the installation. However when I try to use the topo to raster by file < Interpolation < Spatial Analyst Tools I get an error. (see first picture)

however I know it's been installed correctly and ArcGIS Administrator also verifies that no issues should be occurring. (see second image.)

Any ideas as to what could be causing this?

thank you!

simple...go to the Customize, Extensions menu and toggle on the Spatial Analyst...registration gives you permission to use it...toggling it on is the 'key'

Thank you so much Dan!
