Unable to create this part due to an internal error. Reason for the failure: java.io.FileNotFoundException (The system cannot find the path specified)

Every time I try to open definition of a function on CCS 4 I get this error.

From what I understand here, its because I m using a workspace from a different PC (C:\Users\Supriya\Desktop). How can I change the path below?
