incorrect path to shell??

Hello, I am new to the Altera environment.

I have the Terasic DE1 development board and have been trying to

build and download to it for some time. I have yet to be able to build both a fpga image (with NIOS) and a NIOS application.

My current problem is with SOPC builder. It fails.

I should note that I have just recently upgraded to 9.0 web tools.

I am running on Windows Vista.

Here is the error output that I am getting when trying to generate.

It looks to me that the shell environment variable is set to "/bin/sh". I beleive this to be incorrect. There is no sh at that location. Shouldn't it be set to "/cygdrive/c/altera/90/quartus/bin/cygwin/bin/sh"? If so how do I set it?

I will appreciate any help provided.
