path = "C:\\Program Files\\DIGISPORT\\first.xml";
                path2 = "C:\\Program Files\\DIGISPORT\\";
                          CI_CompileProgram(path, path2);

As control hits CI_CompileProgram(path,path2); Exception occurs... I couldn't find any solution on google... Any help would be appreciated ..
Thank you,

The most likely reason is that the "Program files" folder and it's subfolders are not normally write access permitted - and for good security reasons. Since it would appear that you are trying to compile somthing into a folder, you will probably have to either have admin privileges, or (possibly, I haven't tried) give full access to everybody to the DIGISPORT folder. I wouldn't though - I would store my data elsewhere that doesn't need special permission!
