Opening *.eps files with GIMP

I installed GIMP on my system and needed to edit *.eps files. On trying to open an *.eps file, I got an error which did not allow me to open these files since I did not have Ghostscript installed on my system. Even after installing Ghostscript, I saw the same error on trying to open the file. The solution to this was to add an environment variable in Windows to tell GIMP where to look for Ghostscript to open these files. The procedure for this is:
1. Right click on "My Computer" and select "Properties".
2. In the tab "Advanced", select "Environment Variables".
3. In the window on the top, click "New".
4. Variable name: GS_PROG
5. Variable value: C:\Program Files\gs\gs8.64\bin\gswin32.exe (This is the path of the Ghostscript variable on your system).
6. Restart GIMP.

Update (07/19/2011):
In Windows 7, there are 2 types of environment  variables - System variables and User Variables. System variables apply for all users, while User variables only applies for the current user.
