6.1i ISE - Error: "Unable to open the project file: '...\Project.npl' because the file cannot be found"


Keywords: ISE, Foundation, unable, open, create, temp, project, file, installation

Urgency: Standard

General Description:
From ISE, select File -> New Project, and the following error appears:

"Unable to open the project file: '<Project_directory>\<Project>.npl' because the file cannot be found."

followed by:

"Unable to create the temp project '<Project_directory>\<Project>.npl'."



Be sure that your Xilinx environment variable points to the directory in which the ISE tools are installed. (The default directory is c:\xilinx.)


Additionally, ensure that you are clicking the Windows icon that corresponds to the ISE directory and executables.


If you did not set the environment variable properly and/or click the icon that corresponds to the correct directory, you might see a "launch window" that displays:

"Release Version: 6.1i
Application Version: build+G-XX+00"

where "XX" is a number between 19 and 27.
