Error insatlling Tools in Debian

Hi everyone,

I have searched through the net looking for an answer for my problem,  but have been unsuccessful.  I have a Win 7 Pro, and I installed Debian  as guest and installed the updates and kernel headers.  I then tried to install  the VMWare Tools, but it fails with the following:

*****
Searching for a valid kernel header path...
The path ""is not a valid path to the 2.6.32-5-amd64 kernel headers. 
Would you like to change it?

Enter the path to the kernel header files for the 2.6.32-5-amd64 kernel? /usr/src/linux-headers-2.6.32-5-amd64/include/linux

The path "/usr/src/linux-headers-2.6.32-5-amd64/include/linux" is not a valid path to the 2.6.32-5-amd64 kernel headers.
Would you like to change it? [yes]

Any help would be appreciated!  Thanks in advance.
